Reximex RP PCP Pistol/Carbine – Regulated Compact PCP with Detachable Stock, Side Lever and Multi-Shot Capability

The Reximex RP PCP Pistol/Carbine is a lightweight regulated pre-charged pneumatic platform designed to bridge the gap between a compact air pistol and a shoulder-supported carbine. Its detachable synthetic stock allows the setup to be configured for different lawful sporting and recreational shooting styles, while the compact aluminum frame keeps overall weight low and handling straightforward.

Reximex currently offers the RP in .177 / 4.5mm and .22 / 5.5mm. The manufacturer lists a side-lever action, standard regulator, removable 50cc aluminum air tube, 250 BAR fill pressure, adjustable sights, moderator-ready muzzle arrangement, and removable stock. Overall length is approximately 330mm in pistol form, barrel length is 200mm, and weight is about 900 grams.

Why Choose the Reximex RP?

The strongest reason to choose this platform is flexibility.

It can be used as a compact pistol-style setup or fitted with the detachable stock for a more stable carbine-like shooting position. That gives the shooter two distinct handling styles without requiring a completely different airgun.

The regulated action is another important advantage. A regulator helps manage working pressure so successive shots are delivered more consistently within the usable fill range.

For recreational target shooting, this combination of compact size, repeatable pressure management, and removable stock makes the platform practical and easy to configure.

How Good Is the Regulated System?

Reximex lists the regulator as standard equipment.

A regulated pneumatic system can improve shot-to-shot consistency because the firing valve receives a more controlled amount of pressure rather than relying directly on the changing pressure inside the main reservoir.

This becomes particularly useful during longer target sessions.

However, actual performance still depends on pellet weight, temperature, elevation, pressure level, and mechanical condition.

The manufacturer itself notes that published velocity and energy values may vary with these factors.

Caliber Options and Published Output

The RP is available in two calibers.

For .177, Reximex lists a maximum velocity of approximately 610 fps and energy around 9.5 joules / 7 ft-lb.

For .22, maximum velocity is approximately 515 fps with energy around 14.5 joules / 10.7 ft-lb.

These figures are manufacturer test values, not guaranteed results under every condition.

Searches such as tps to joules calculator, Tps joule calculator, fps to ft Ibs, and airgun joules calculator can help users convert units, but chronograph testing remains more useful when actual output needs to be confirmed.

Magazine Capacity

Magazine capacity changes according to caliber.

The .177 version uses a 9-shot magazine, while the .22 version uses a 7-shot magazine.

This gives the shooter convenient multi-shot capability while retaining a very compact overall format.

The magazine should be loaded carefully so pellet skirts are not damaged.

Smooth indexing and correct seating help preserve reliable feeding.

Shot Count and Air Efficiency

The 50cc removable aluminum air tube is compact, yet the regulated system provides a useful number of shots.

Reximex lists approximately 55 shots in .177 and 40 shots in .22 through the optimal pressure range.

That makes the platform suitable for shorter target sessions without requiring an oversized reservoir.

The air tube can also be removed, which makes servicing and handling more convenient.

250 BAR Fill Pressure

Maximum fill pressure is listed at 250 BAR.

Filling should always be carried out with compatible high-pressure equipment.

The connection should be kept clean, pressure should be increased gradually, and the stated maximum should never be exceeded.

Pressure-bearing components should not be modified casually.

Side-Lever Operation

The cocking system uses a side lever positioned on the left side of the action.

This arrangement allows the action to be cycled with a relatively short movement.

For supported target shooting, that can help the shooter preserve shoulder and cheek placement when the stock is fitted.

The lever should always be operated fully and smoothly.

Detachable Stock

One of the platform’s defining features is the removable high-quality synthetic stock.

With the stock removed, the setup remains compact and pistol-like.

With the stock fitted, the shooter gains a more stable shoulder contact point and a longer overall handling geometry.

This adaptability is one of the main reasons the design stands apart from a conventional fixed-format air pistol.

Adjustable Sights

Reximex equips the RP with adjustable sights, allowing basic sight correction without requiring an optic.

This makes the platform immediately usable for short-range target work.

An 11mm mounting rail is also provided, allowing compatible sighting equipment to be installed where legally and practically appropriate.

The manufacturer notes that a scope is not included.

Moderator-Ready Muzzle

The muzzle is designed to accept compatible moderation equipment where legally permitted.

This should not be interpreted as meaning a moderator is included.

Local rules concerning sound moderators vary considerably, so legal requirements should always be checked before purchase or installation.

Reximex and Related Model Searches

The broader reximex and reximex airguns catalogue includes a wide variety of pneumatic platforms.

Searches for reximex throne gen2, reximex throne gen 2, reximex mito, reximex mitos, reximex гр, reximex rра, and reximex lieva may lead buyers toward different products within the same brand ecosystem.

Reximex currently lists the RP, RPA, RP 11, Accura, Lyra-K, Throne Gen2, Meta, Daystar and several other models as separate platforms.

Their specifications should not be mixed.

Accura and RP Comparison Search Intent

The phrase reximex accura pcp air rifle refers to a different full-size rifle platform.

The Accura uses a much larger reservoir and is designed around a conventional rifle format, while the RP is built as a compact pistol/carbine system.

This distinction matters when comparing size, shot count, weight, ergonomics, and intended use.

Reximex Lyra K Related Searches

Searches including Reximex Lyra K, Reximex Lyra-K PCP air rifle, Reximex Lyra-K airgun, Reximex Lyra-K review, Reximex Lyra-K PCP rifle, Reximex Lyra-K regulated PCP, Reximex Lyra-K compact PCP rifle, and Reximex Lyra-K tactical air rifle relate to another model family.

Likewise, Reximex Lyra-K hunting rifle, Reximex Lyra-K accuracy test, Reximex Lyra-K scope package, and Reximex Lyra-K pellet gun should not be interpreted as specifications of the RP.

The RP should be evaluated according to its own compact dimensions, removable stock, reservoir size, magazine system, and published power figures.

Buyer-Intent Searches

Commercial search phrases such as buy Reximex Lyra-K online, best price Reximex Lyra-K, gunseek, roxy max, and mx rex represent general shopping or search-engine intent rather than product specifications.

When comparing pneumatic airguns, buyers should focus on verified caliber, energy, reservoir capacity, dimensions, warranty, service availability, and legal requirements.

Pest Control and Small-Game Search Terms

Searches for Reximex Lyra-K for pest control and Reximex Lyra-K small game hunting concern possible uses of another model.

Any lawful live-quarry use should follow local laws, landowner permission, appropriate equipment requirements, and humane practices.

The RP is equally suitable for discussion as a compact recreational and target-shooting platform without assuming that hunting is the buyer’s intended purpose.

Weight and Portability

At approximately 900 grams, the RP is exceptionally light compared with many full-size pneumatic rifles.

This low weight improves portability and makes the system easier to handle during target sessions.

However, lighter weight can also make consistent grip technique more important because small changes in hand pressure may affect stability.

Why the RP Offers Strong Practical Value

The RP combines several useful features in an unusually compact package: regulated performance, multi-shot operation, removable air storage, adjustable sights, lightweight aluminum construction, and a detachable stock.

For lawful recreational and target use, this gives the shooter more configuration flexibility than a conventional fixed-stock rifle or fixed-format pistol.

When correctly filled, properly maintained, paired with suitable ammunition, and operated within local regulations, the Reximex RP PCP Pistol/Carbine offers a practical balance of portability, consistency, compact engineering, and adaptable ergonomics.

Accuracy, Handling, Air Management, Trigger Control, and Practical Shooting Performance

Building Consistent Accuracy

Consistent performance begins with a repeatable shooting position, suitable ammunition, and stable pressure management.

A compact pneumatic platform can deliver very good precision when the shooter controls the main variables that affect each shot.

Grip pressure, sight alignment, trigger movement, breathing, and follow-through should remain as similar as possible from one shot to the next.

Ammunition selection also matters.

Different pellet weights, head sizes, and profiles may produce noticeably different groups from the same barrel.

For that reason, structured testing is more useful than assuming the fastest pellet will automatically be the most accurate.

Pistol and Shoulder-Supported Use

One of the most practical advantages of this platform is the ability to use it in more than one configuration.

Without the rear support fitted, the setup remains compact and easy to handle.

With the rear support installed, the shooter gains an additional contact point against the shoulder, which can improve stability.

The supported configuration may be especially useful during target sessions where repeatable positioning is important.

The preferred setup depends on intended lawful use, comfort, and the type of shooting position being used.

Grip Technique

Grip pressure should remain controlled and consistent.

A compact platform reacts more noticeably to hand movement than a heavier full-length rifle.

Squeezing too hard can introduce unnecessary movement.

A relaxed but secure grip usually produces better repeatability.

The trigger hand should control the platform without pulling it sideways during release.

The supporting hand should stabilize the front without creating unnecessary tension.

Sight Alignment

Correct sight alignment is fundamental to precision.

When using the supplied open sights, the relationship between rear sight, front sight, and target should remain identical for every shot.

If an optic is installed, eye position should remain centered and repeatable.

In the shoulder-supported configuration, the stock can make this easier because the shooter can establish a consistent cheek and shoulder relationship.

Any optic or sight should be mounted securely and checked periodically.

Trigger Control

A clean trigger release helps prevent movement at the moment of firing.

The trigger should be pressed progressively rather than jerked.

The shooter should learn the feel of the first stage and the point where final release occurs.

Once this becomes familiar, the firing cycle becomes more predictable.

Any adjustment should remain within the manufacturer’s safe operating range.

An excessively light setting is not automatically better.

Predictability and safe engagement are more important.

Follow-Through

Follow-through should continue after the shot.

The shooter should maintain the same grip, sight picture, and body position briefly instead of moving immediately.

This helps prevent unnecessary disturbance during the final part of the firing cycle.

It also makes it easier to evaluate technique during group testing.

Good follow-through is especially useful when shooting from a rest because small movements become easier to identify.

Side-Lever Rhythm

The side-lever action can help maintain shooting position between shots.

A smooth and complete operating cycle is preferable to a rushed movement.

The lever should be moved fully through its intended travel and then returned securely.

Partial operation can lead to feeding problems.

A consistent loading rhythm also helps the shooter maintain focus during longer strings.

Magazine Feeding

The rotary magazine should be loaded carefully so pellets remain undamaged.

Bent skirts or poorly seated pellets can affect both feeding and accuracy.

The magazine should rotate smoothly.

If unusual resistance develops, the cause should be identified instead of forcing the mechanism.

Keeping magazines clean and protected from dirt can improve long-term reliability.

Spare magazines should be stored where they cannot be crushed or contaminated.

Single-Shot Testing

Single-shot loading can be useful during initial ammunition testing where available.

Removing magazine indexing from the test can help isolate barrel preference and shooter technique.

Groups should be fired using the same pressure range, support method, and sight settings.

Changing several variables at once makes it difficult to understand the result.

Once a preferred pellet is identified, normal magazine use can resume.

Managing Air Pressure. 

The compact reservoir provides a limited but useful number of shots.

Pressure should therefore be monitored throughout the session.

Performance may change as pressure drops below the most consistent working range.

The shooter should become familiar with how many accurate shots are available from a normal fill.

Recording starting and ending pressure can help establish a reliable shooting routine.

Filling Technique

The reservoir should be filled slowly using compatible high-pressure equipment.

The connection should remain clean.

Dust, moisture, or debris entering the fill system can affect internal seals and valves.

Pressure should be observed throughout charging.

The stated maximum should never be exceeded.

A controlled fill reduces heat buildup and makes it easier to stop at the correct pressure.

Regulated Performance

A regulated pneumatic system is designed to provide more consistent working pressure through much of the usable fill.

This supports more predictable velocity and point of impact.

However, the regulator is only one part of the complete system.

Ammunition, temperature, mechanical condition, and pressure level still influence performance.

If shot consistency changes noticeably, these factors should be considered before assuming a regulator problem.

Chronograph Testing

A chronograph can provide useful data about shot-to-shot velocity.

Consistent velocity often supports consistent vertical point of impact.

However, numerical speed should not replace actual target testing.

A pellet that produces slightly lower velocity may still group much better.

The best setup is usually the one that combines stable output with reliable accuracy.

Group Testing

Groups provide more useful information than individual shots.

Several carefully fired shots reveal whether the platform, ammunition, and shooter technique are working consistently.

Testing should be completed under similar conditions whenever possible.

Wind, pressure level, support method, and fatigue can all affect the result.

One unusually small group should not automatically be treated as the final answer.

Repeatability across several groups is more valuable.

Supported Shooting

A rest can help reveal the mechanical accuracy potential of the platform.

The front should be supported consistently without being clamped excessively.

The shoulder-supported configuration can provide additional stability.

Grip pressure and cheek contact should remain the same for each shot.

A natural position is generally better than forcing the setup into alignment.

Unsupported Shooting

Unsupported use requires more body control.

The shooter should avoid excessive muscular tension.

Shorter practice strings can be more productive because fatigue develops faster when the entire platform is supported by the arms.

Accuracy should be developed gradually.

Consistent technique matters more than firing a large number of shots quickly.

Managing Refill Timing

The relatively small reservoir means refill timing is part of normal ownership.

The shooter should avoid waiting until performance has clearly deteriorated before refilling.

Instead, the useful pressure window can be identified through testing.

This makes sessions more predictable and prevents wasted shots at pressures where consistency may begin to change.

Environmental Conditions

Temperature can influence stored pressure and operating behavior.

Wind can also affect lightweight projectiles significantly at longer distances.

For that reason, changes in point of impact should not always be blamed on the sight or mechanical system.

Environmental conditions should be considered whenever groups are compared.

A calm indoor range can provide a useful baseline for testing.

Optic Security

If an optic is fitted, mounting hardware should remain secure.

Even small movement can change the point of impact.

Screws should be checked periodically but should not be over-tightened.

The optic should be positioned so the shooter can obtain a clear sight picture without stretching or twisting the head.

Correct placement improves both comfort and consistency.

Cleaning and Barrel Care

The barrel should be cleaned only when necessary and with suitable materials.

Aggressive or frequent cleaning can create unnecessary wear.

The muzzle crown should be protected because damage in this area can affect pellet exit consistency.

If accuracy remains stable, routine external care may be enough.

When groups deteriorate unexpectedly, ammunition, optic security, pressure, and technique should be checked before assuming the barrel needs cleaning.

Managing Shooter Fatigue

Fatigue can reduce accuracy without being immediately obvious.

Grip pressure may change.

Trigger control may become rushed.

Sight alignment may become inconsistent.

Taking short breaks helps maintain concentration.

A poor group fired late in a session should not automatically be used to judge the platform’s capability.

Long-Term Practical Performance

A compact regulated pneumatic platform can deliver very useful accuracy when shooting technique, pressure management, ammunition selection, and sight setup are handled consistently.

Its light weight and configurable format make it practical for controlled target use, but those same characteristics reward disciplined handling.

When the shooter develops a repeatable grip, monitors pressure carefully, tests ammunition systematically, maintains secure sighting equipment, and uses smooth trigger control, the platform becomes easier to understand and more predictable across a wide range of lawful recreational shooting situations.

Shooting Technique, Stability, Accuracy Development, Setup Refinement, and Consistent Results

Developing a Repeatable Shooting Position

A compact pneumatic platform benefits greatly from a consistent shooting position.

The relationship between the hands, shoulders, head, sights, and trigger should remain as similar as possible from one shot to the next.

Small changes in grip or head position can shift the sight picture and reduce consistency.

The goal is to create a natural position that does not require excessive muscular effort.

When the setup fits correctly, the shooter should be able to raise or shoulder the platform and obtain the same sight alignment repeatedly.

Grip Consistency

Grip pressure has a noticeable influence on lightweight shooting platforms.

An overly tight grip can introduce unwanted movement, while a grip that is too loose can reduce control.

The best approach is firm enough for stability but relaxed enough to avoid unnecessary tension.

The trigger hand should remain comfortable, and the supporting hand should steady the front without twisting the platform.

Consistency matters more than force.

Shoulder-Supported Stability

When the rear support is fitted, the shooter gains an additional point of contact.

This can improve stability by creating a repeatable relationship between shoulder, head, and sights.

The rear section should rest naturally against the shoulder.

Excessive pressure is unnecessary and may create tension through the upper body.

A light and consistent contact point usually produces better repeatability.

Head Position

Head position should remain stable.

The eye should line up naturally with the sighting system without requiring excessive neck movement.

If the shooter has to stretch forward or tilt the head repeatedly, the setup may need refinement.

A comfortable sight picture helps reduce fatigue.

It also improves the chance that each shot begins from the same visual alignment.

Open-Sight Technique

With open sights, the front and rear elements should remain aligned consistently.

The front sight should be centered in the rear reference.

The shooter should focus on maintaining the same sight relationship before every shot.

Small alignment errors can create noticeable point-of-impact differences.

For this reason, sight picture consistency is often more important than trying to hold perfectly motionless.

Optic Use

If an optic is installed, eye relief and height should be checked carefully.

The shooter should obtain a full and clear sight picture without moving the head unnaturally.

Mounting hardware should remain secure.

Once the optic is positioned correctly, unnecessary repositioning should be avoided.

A stable optic setup makes it easier to identify whether changes in accuracy come from ammunition, pressure, or technique.

Trigger-Finger Placement

The trigger finger should contact the trigger naturally.

Too much finger may pull the platform sideways.

Too little contact can make the movement feel awkward.

The finger should move independently from the rest of the hand.

This helps prevent grip pressure from changing during release.

A smooth straight-back movement generally provides the most repeatable result.

Trigger Release

The final release should be controlled rather than anticipated.

Jerking the trigger often moves the sights just before the shot.

The shooter should build pressure progressively while maintaining alignment.

With practice, the release becomes more predictable.

The goal is not an unexpectedly light trigger but a repeatable and safe one.

Breathing Control

Breathing affects movement.

The shooter should avoid holding the breath for too long.

A natural pause after exhalation often provides a stable moment for the shot.

If the position becomes strained, the shooter should reset.

A comfortable breathing rhythm helps maintain concentration during longer target sessions.

Follow-Through

Follow-through is important even with a low-recoil pneumatic system.

The shooter should keep the sights aligned and maintain the same grip briefly after the shot.

Moving the head or hands immediately can make it harder to judge technique.

Good follow-through also encourages a more disciplined firing rhythm.

Establishing a Consistent Rhythm

A repeatable rhythm can improve accuracy.

The process may include aligning the sights, controlling breathing, applying trigger pressure, firing, maintaining follow-through, cycling the action, and resetting.

Rushing this sequence can introduce errors.

A steady rhythm supports concentration and makes performance easier to evaluate.

Ammunition Testing

Different pellets can behave differently in the same barrel.

Testing several suitable options is therefore useful.

The shooter should compare groups using similar conditions.

Pressure, support method, distance, and sight settings should remain unchanged where possible.

Changing one variable at a time produces more useful information.

Pellet Condition

Pellets should be inspected before loading.

Damaged skirts or visibly distorted heads can affect both feeding and accuracy.

A quick visual check is usually enough.

Obviously damaged pellets should be removed from the test.

This helps ensure that poor results are not caused by defective ammunition.

Group Evaluation

A group provides better information than a single shot.

Several shots fired with consistent technique reveal whether the setup is performing predictably.

The shooter should compare multiple groups rather than choosing one unusually small result.

Repeatability matters more than occasional luck.

Pressure and Group Consistency

Pressure should be recorded during testing.

The platform may perform most consistently within a certain portion of the fill.

Comparing groups fired at very different pressures can create misleading conclusions.

A simple record of starting and ending pressure helps identify the most consistent operating range.

Chronograph Data

Velocity data can help explain changes in vertical impact.

If the speed varies considerably from shot to shot, grouping may also become less consistent.

However, a perfectly stable velocity does not guarantee the best group.

Mechanical consistency and pellet compatibility must work together.

Target results remain the final practical test.

Supported Testing

A stable rest is useful for establishing a baseline.

The support should hold the platform naturally rather than clamp it rigidly.

The same contact points should be used for each shot.

This reduces variables and helps reveal the actual performance of the setup.

Unsupported Practice

Unsupported shooting requires more balance and muscle control.

Short sessions are usually more productive than long ones.

As fatigue develops, the hands and shoulders begin to move more.

Technique can deteriorate gradually.

Stopping before fatigue becomes severe helps preserve useful practice.

Standing Position

In a standing position, the shooter should avoid excessive tension.

The supporting arm and body should work together to create a natural hold.

The platform should feel balanced rather than forced into position.

A stable stance is more important than trying to eliminate every small movement.

Sitting and Rested Positions

Sitting or supported positions can improve stability.

Elbows, knees, or a rest can provide additional support depending on the shooting environment.

The same grip, head position, and trigger technique should still be maintained.

These positions are useful for testing because they reduce movement without requiring a full bench setup.

Zero Refinement

Once a suitable pellet is selected, zero can be refined.

Adjustments should be small and deliberate.

The shooter should fire another group after each change.

Repeatedly adjusting the sights after every single shot can make the process confusing.

A group-based approach provides more reliable information.

Environmental Awareness

Wind, temperature, and lighting conditions can affect results.

A crosswind can shift lightweight projectiles noticeably at longer distances.

Temperature can influence pressure behavior.

Changing light can affect how open sights appear.

These variables should be considered when comparing results from different sessions.

Maintaining Notes

A simple range log can improve long-term consistency.

Useful information includes pellet type, distance, pressure, sight settings, group size, weather, and shooting position.

Over time, the shooter can identify patterns that are difficult to remember accurately.

This makes future setup decisions more informed.

Identifying Mechanical Changes

A shooter who knows the platform well can recognize changes more easily.

A different cocking feel, unusual trigger response, altered point of impact, or changing pressure behavior may indicate a maintenance issue.

Repeated changes should be investigated.

Technique should not be used to compensate indefinitely for mechanical problems.

Managing Fatigue

Fatigue affects grip, sight alignment, breathing, and trigger control.

The shooter should recognize when performance begins to decline.

Short breaks can restore concentration.

A poor group late in the session may reflect fatigue rather than equipment performance.

Building Long-Term Familiarity

Consistent results develop over time.

The shooter learns how the platform balances, how the trigger feels, which pellets perform best, and how pressure changes through the fill cycle.

This familiarity makes the system easier to use and easier to evaluate.

When technique, ammunition, pressure management, sight setup, and maintenance are handled consistently, the platform becomes increasingly predictable and capable across lawful recreational and precision-focused target shooting.
