Reximex Nyx Compact PCP Airgun

A compact tactical platform is presented by the Reximex Nyx Compact PCP Airgun, and a regulated pre-charged pneumatic system is combined with AR-inspired adjustability so that precision can be pursued by shooters of every experience level. Maneuverability is prioritized by the shortened chassis, while consistent power, multi-shot convenience, and field-ready mounting options are still retained. Consequently, pest control, small-game hunting, plinking, and range practice can all be approached with one adaptable rifle.

Moreover, a modern sidelever action is employed so that follow-up shots can be cycled smoothly. Meanwhile, an adjustable regulator and an external valve power knob are provided so that output can be tuned to pellet choice, distance, and local power limits. Therefore, the same platform can be configured for sub-12 ft-lbs environments or, where lawful, for higher-energy FAC use.

Key Features of the Reximex Nyx Compact PCP Airgun

The following capabilities are built into the rifle so that handling, consistency, and accessory flexibility can be maximized:

• A regulated PCP action is used, and shot-to-shot consistency is supported across the usable pressure band.
• A precision-rifled barrel with an integrated moderator is fitted, and extra 1/2″ UNF muzzle threading is retained for an additional silencer when quieter shooting is required.
• A removable 425 cc aluminum air bottle is installed, and a maximum fill of 3,625 PSI / 250 bar is supported.
• Approximately 75 shots at optimal velocity are delivered in .22 and .25 when pressure is kept between 3,625 PSI and 1,595 PSI (250–110 bar).
• Magazine capacities of 14 rounds (.177), 12 rounds (.22), and 10 rounds (.25) are supplied, and two magazines are included so that reloads can be completed quickly.
• Lead-pellet velocities of up to 900 fps in .22 and 800 fps in .25 are published for high-power configurations, and muzzle energies of up to 32.6 fpe (.22) and 36.09 fpe (.25) are listed for FAC-legal setups.
• An externally adjustable valve power knob is located on the action so that output can be reduced or increased without tools being opened inside the receiver.
• A two-stage adjustable trigger is fitted, and a crisp, predictable break can be dialed in for each shooter.
• An AR-compatible textured pistol grip and a telescoping buttstock are used, and an elevation-adjustable cheekpiece is included so that length of pull and eye alignment can be customized.
• A Picatinny optics rail is mounted on top, and additional Picatinny rails are placed under the bottle and under the buttstock so that bipods, lights, and other accessories can be attached.
• A manual safety, a bottle pressure gauge, and a male Foster quick-disconnect fill fitting are provided, and a matching female Foster adapter is included in the box.
• A compact overall length of approximately 31.5–34.5 inches (about 800–880 mm, depending on stock setting) is achieved, and a barrel length of 14.96 inches (380 mm) is used.
• An approximate weight of 7.7 lb (3.5 kg) is maintained so that the rifle can be carried for extended sessions without unnecessary bulk.

In addition, a single-shot tray is commonly supplied with Reximex magazines, so precision work from a rest can be practiced when magazine feeding is not preferred.

Calibers, Power, and FAC Considerations

Caliber choice is offered in .177, .22, and .25 so that the Reximex Nyx Compact PCP Airgun can be matched to the intended task. Target work and high shot counts are often favored in .177, while a practical balance of trajectory and energy is typically selected in .22. Meanwhile, extra downrange authority for small game and tougher pests is provided by .25 where regulations allow.

Furthermore, factory power is market-dependent. Sub-12 ft-lbs output is commonly supplied in UK-legal examples, and shot counts in those configurations are frequently quoted in the 130–150 range depending on caliber and tune. Conversely, higher-energy FAC versions are listed with the 900 / 800 fps and 32.6 / 36.09 fpe figures above. Accordingly, local airgun laws, licensing, and energy limits must always be verified before a configuration is ordered or used.

Likewise, the external power knob and regulator work together so that velocity can be lowered for closer work or raised for longer shots. As a result, pellet wastage is reduced and grouping can be tightened once a preferred ammunition is found.

Ergonomics, Stock Adjustment, and Optics Ready Layout

Comfort for a wide range of body types is supported by the telescoping AR-style stock. Length of pull can be changed in seconds, and cheek height can be raised or lowered until a consistent sight picture is obtained. Subsequently, fatigue is reduced during longer sessions because the rifle can be fitted to the shooter rather than the reverse.

Moreover, the textured grip is designed for a secure hold in wet or gloved conditions. In the same way, accessory rails allow a bipod to be mounted under the bottle for prone or bench work, while a sling, monopod, or other support can be attached at the rear rail. Therefore, the same compact chassis can be used from a vehicle window, a hide, or an open range without a second rifle being required.

Notably, the Picatinny top rail accepts a wide choice of scopes, red dots, and compact optics. Because no iron sights are fitted, an optic is recommended from the first outing so that the accuracy potential of the rifled barrel can be realized.

Practical Use of the Reximex Nyx Compact PCP Airgun

Field handling is simplified by the short overall length. Tight woodland paths, farm buildings, and vehicle-based pest routes can be negotiated more easily than with a full-length bottle rifle. Meanwhile, the integrated moderator keeps report at a medium level, and an extra 1/2″ UNF can is still available when even quieter shooting is needed around livestock or dwellings.

Additionally, the sidelever can be operated without the rifle being taken far off the shoulder, so follow-up shots on multiple pests can be taken promptly. After the magazine is emptied, a second loaded magazine can be inserted so that the session is not interrupted. Consequently, time on target is increased and air is used more efficiently across the 75-shot optimal window (high-power figures) or the higher counts of legal-limit tunes.

On the range, the adjustable trigger and regulator allow groups to be refined with JSB-class pellets in the published test weights (approximately 18.13 gr in .22 and 25.39 gr in .25 for the high-power data). Consistency within a few feet per second over a short string has been reported on regulated examples, provided dry air and a correct fill are used. Therefore, zero can be trusted from the first shot of a session to the last usable pressure on the gauge.

Responsible use remains essential. Safe backstops must be confirmed, local regulations must be followed, and dry compressed air only must be used at or below the 250 bar maximum. In addition, the bottle should be protected from extreme heat, and fill equipment with a working gauge should always be employed.

Filling, Maintenance, and What Is Included

Filling is completed through the Foster quick-disconnect interface. After the rifle is placed on safe and unloaded, the supplied female adapter can be connected to a hand pump, compressor, or scuba setup rated for 250 bar. Subsequently, pressure is monitored on the onboard bottle gauge so that overfilling is avoided.

Routine care is straightforward. The barrel and O-rings benefit from periodic light lubrication with airgun-safe oil, magazines should be kept clean and dry, and the regulator and valve should not be disassembled by untrained hands. Likewise, threads on the muzzle cap should be checked before an extra moderator is fitted so that alignment is preserved.

Two magazines, the Foster fill adapter, and the threaded muzzle cap are typically included so that the Reximex Nyx Compact PCP Airgun can be put into service immediately after an optic is mounted and a zero is established.

Why This Compact PCP Belongs in the Kit

Value is concentrated in a short, regulated, AR-adjustable package. Power can be tuned, magazines can be swapped quickly, and accessories can be added without aftermarket chassis work. Ultimately, a capable all-rounder is offered to hunters, pest controllers, and recreational shooters who want modern handling without a full-size bottle rifle being carried.

When lawful ownership, safe storage, and correct filling practices are observed, dependable performance can be expected from the first fill to the last regulated shot. The Reximex Nyx Compact PCP Airgun is therefore ready to be specified with the caliber and power level that match your ground, your local rules, and your preferred style of shooting

Calibres, FAC, Power and Accessories for the Reximex Nyx Compact PCP Airgun

Calibre selection is offered on the Reximex Nyx Compact PCP Airgun so that trajectory, energy, and magazine capacity can be matched to the intended use. Meanwhile, power output is market-dependent, and both legal-limit and FAC configurations are supplied. Consequently, accessories already built into the platform can be used to refine fit, mounting, and sound control without a second rifle being purchased.

Available Calibres and Magazine Capacity

Three pellet calibres are commonly listed so that every shooter can choose the balance of speed, knock-down, and shot count that suits their ground.

• .177 (4.5 mm) is typically paired with a 14-shot rotary magazine. A flatter trajectory is delivered at legal-limit energy, and high shot counts are often recorded when the regulator is set for sub-12 ft-lbs use. Therefore, paper, spinners, and HFT-style practice are frequently favoured in this calibre.
• .22 (5.5 mm) is supplied with a 12-shot magazine. A practical mix of pellet weight and retained energy is provided, and this calibre is widely chosen for pest control and general hunting where a versatile all-rounder is required.
• .25 (6.35 mm) uses a 10-shot magazine. Greater pellet mass and published FAC energy are available, and tougher small game or longer pest shots can be approached when local law permits the higher output.

In addition, two magazines are normally included in the box, and a single-shot tray is frequently supplied with Reximex index magazines. After the rotary magazine is removed, precision loading from a rest can therefore be practised when magazine feeding is not preferred. Likewise, maximum projectile length is limited on some listings (around 10 mm), so slug or extra-long pellet use should be confirmed before those projectiles are purchased.

Moreover, grouping quality still depends on pellet match rather than calibre name alone. JSB-class pellets in the published test weights (approximately 18.13 gr in .22 and 25.39 gr in .25 for high-power data) are commonly used as a starting point. Subsequently, several tins should be tested at the chosen power setting until a consistent point of impact is established.

Legal-Limit Power Versus FAC Output

Power is not fixed at a single figure. An adjustable regulator is fitted, and an externally accessible valve power knob is provided on the action so that output can be raised or lowered without the receiver being opened. As a result, the same rifle can be tuned for quiet close work or for longer shots, provided the configuration remains legal in the country of use.

In many UK and similar markets, a legal-limit tune of approximately 10.8–11.8 ft-lbs is supplied. Under that restriction, published shot counts are often quoted around 130 in .177 and 150 in .22 from the 425 cc bottle when the rifle is filled toward 250 bar and used through the regulated band. Consistency within a few feet per second over a short string has been reported on regulated examples when dry air and a correct fill are used. Therefore, a full magazine can usually be emptied before a refill is required on a typical pest or range session.

Where FAC (or equivalent unrestricted) ownership is lawful, higher factory figures are published:

• In .177, up to about 1,000 fps and 18.7 ft-lbs (25.4 J) are listed, with around 90 effective shots.
• In .22, up to about 900 fps and 32.6 ft-lbs (44.3 J) are listed, with about 75 shots at optimal velocity between 3,625 PSI and 1,595 PSI (250–110 bar).
• In .25, up to about 800 fps and 36.09 ft-lbs (48.9 J) are listed, again with about 75 shots in the same pressure window.

Accordingly, FAC energy must never be assumed on a rifle that was sold as a legal-limit example. Local licensing, transport rules, and energy limits must be verified before a high-power configuration is ordered, imported, or used. Furthermore, lowering the power knob on an FAC rifle can still be useful for indoor ranges, close pests, or quieter work around livestock, while the regulator continues to hold velocity steady across the usable fill.

Fill pressure remains 250 bar / 3,625 PSI on the standard 425 cc removable aluminium bottle. Only dry compressed air may be used. Heat-soaked bottles, overfills, and unregulated filling equipment must be avoided so that safety and regulator life are protected.

Accessories, Rails, and Ready-to-Fit Options

A conversion-focused accessory layout is already built into the Reximex Nyx Compact PCP Airgun so that optics and supports can be added immediately.

• A full-length Picatinny / Weaver optics rail is mounted on top. Scopes, compact variables, and red-dot sights can therefore be fitted without a separate rail kit being sourced. Because iron sights are not provided, an optic should be mounted before the first zeroing session.
• Additional Picatinny rails are placed under the air bottle and under the buttstock. A bipod can be attached at the front rail for prone or bench work, while a sling stud adapter, rear bag stop, or compact accessory can be fitted at the rear.
• An AR-compatible textured pistol grip and an AR-compatible telescoping buttstock are used. Aftermarket AR grips and selected stock furniture can often be exchanged when a different texture or angle is preferred, provided compatibility is confirmed.
• An elevation-adjustable cheekpiece and an adjustable butt pad are included so that eye alignment and length of pull can be set for shooters of different statures and clothing layers.
• The muzzle is finished with an integrated moderator plus a 1/2″ UNF threaded cap. An extra silencer can be added when even lower report is required, though point of impact should be rechecked after any muzzle device is fitted.
• Filling is completed through a male Foster quick-disconnect. A matching female Foster adapter is included so that a hand pump, compressor, or scuba whip can be connected without a proprietary probe being hunted down.
• A bottle pressure gauge is fitted near the cylinder neck, and a manual safety is provided. Fill status and safe handling can therefore be checked at a glance before the sidelever is cycled.

In the same way, two magazines and the fill adapter arrive in the carton so that the rifle can be put into service after an optic and pellets are added. Scope rings, a bipod, a sling, extra magazines, a compact compressor or pump, and a quality 1/2″ UNF moderator are the most useful first upgrades. Likewise, a hard case sized for a 32–35 inch overall length protects the adjustable stock and bottle during transport.

Ultimately, calibre, legal power, and accessories should be chosen together. A .177 legal-limit setup with a light scope suits high-volume practice; a .22 with bipod and moderator suits mixed pest work; a licensed FAC .25 with a robust optic suits longer, heavier shots where the law allows. When those choices are aligned with local regulations and safe filling practice, the compact regulated platform can be used confidently from the first fill to the last consistent shot on the gauge.

Practical Use in the Field and on the Range

Everyday shooting is shaped by ground, weather, distance, and the need for a short, quiet, adjustable rifle. A compact regulated pre-charged platform is therefore used in places where a long bottle gun would snag on gates, cab roofs, or young woodland. Meanwhile, a sidelever action, a telescoping stock, and a moderated barrel allow sessions to be completed with less fatigue and fewer refill stops when the fill and pellet are matched to the task.

Tight Cover, Yards, and Outbuildings

Movement through narrow alleys, feed stores, and stacked pallets is made easier when overall length is kept short. After the stock is collapsed, the rifle can be carried muzzle-down or across the chest without door frames being struck. Subsequently, the stock can be extended again so that a full cheek weld is restored before the first shot is taken.

Rats, feral pigeons, and similar pests around buildings are often engaged at close to medium range. A legal-limit tune is commonly preferred in those settings so that over-penetration is reduced and neighbours are less likely to be disturbed. In addition, the integrated moderator keeps report at a medium level, and an extra threaded can may be fitted when livestock or dwellings sit close to the line of fire. Consequently, shots can be taken from a doorway or a loft hatch without the rifle being swung through a wide arc.

Gloved hands are frequently required in winter yards. A textured pistol grip is therefore relied upon so that the rifle is not shifted in the hand when frost or rain is present. Likewise, the manual safety can be operated with a thumb without the trigger guard being fished for in poor light. After the shot is taken, the sidelever is cycled while the muzzle remains pointed at a safe backstop, and a second pellet is chambered without the rifle being lowered far from the shoulder.

Highlighted points for yard and building work include:

• A short overall length is used so that corners and doorways can be negotiated.
• A quieter muzzle is favoured so that stock animals are less likely to be scattered.
• A lower power setting is selected when walls, machinery, or public paths sit beyond the target.
• A solid backstop of earth, a purpose-built trap, or a verified safe area is confirmed before any shot is released.

Moreover, magazine capacity is used in bursts rather than in long strings. Two or three carefully placed shots are usually enough on a small group of pests, after which the area is watched again. Therefore, air is conserved and the bottle gauge remains in the regulated band for the rest of the round.

Farm Pest Routes and Vehicle Work

Longer days on mixed farmland are supported when the rifle can be slid behind a seat or into a slip without a full-length cylinder dominating the cab. After arrival at a gate or a silage clamp, the rifle is uncased, the stock is set to the clothing worn that day, and the optic is checked against a known mark if light has changed.

Corvids, rabbits, and similar species on permitted ground are often approached from a vehicle window or a field margin. A bipod can be attached to the rail under the bottle so that a stable rest is obtained on a bonnet bag or a fence post. Meanwhile, the rear rail accepts a sling so that the rifle can be carried across a pasture when the vehicle is left behind. As a result, the same outfit is used for a dawn circuit and a late-afternoon walk without a second gun being packed.
