Reximex NYX Compact 4.5mm PCP Air Rifle with Regulator

Reximex NYX Compact is a modern, compact PCP air rifle featuring a practical tactical stock with a pistol grip. Thanks to its telescopic AR-style buttstock and adjustable cheek rest, the rifle can be fully customized to the shooter's preference. A large-capacity 425cc air cylinder caters to fans of extended shooting sessions without worrying about frequent refills. The rifle is outfitted with a precision rifled barrel with an integrated suppressor, a pressure regulator, a biathlon-style side lever action, a 22 mm optics rail, and a match-grade trigger with an adjustable pull weight. Available calibers include: .177 (4.5 mm), .22 (5.5 mm), and .25 (6.35 mm).

SL – (Side Lever): a biathlon-style two-stroke cocking lever mounted on the right side of the receiver.

Power Regulator – An adjustment knob next to the magazine port allows you to fine-tune muzzle energy based on distance or application (available only in the FAC version).

Barrel – High-precision rifled barrel measuring 14.96" (380 mm), fully shrouded in a metal sleeve and finished with an integrated SilentForce internal suppressor that reduces shot noise. This configuration preserves maximum muzzle energy, often compromised when using optional moderators, while improving the rifle’s overall balance. Add-on moderators may reduce pellet velocity and necessitate re-zeroing optics due to altered ballistics. Barrel quality is a critical factor influencing accuracy, especially at long distances.

Power Source – Compressed air delivered from a 7075 aircraft-grade aluminum cylinder located beneath the barrel, with a capacity of 425cc and fill pressure of 250 bar. When fully charged, the rifle delivers between 75 and 90 effective shots, depending on caliber (FAC version only). An integrated pressure gauge allows you to monitor air levels and charging status. Manufacturer recommends a minimum working pressure of 110 bar.

Stock – Tactical-style design with an ergonomic, rubberized pistol grip for improved handling and shooting stability. Constructed from a combination of black-anodized aluminum and durable polymer in matte black finish. The telescopic buttstock with adjustable cheek rest ends with a rubber recoil pad. Both the stock and grip are AR-compatible, offering broad customization options.

Mounting Rail – A standard 22 mm Weaver/Picatinny rail (MIL-STD 1913 compliant) for mounting optics. The rail is machined from a single piece of aluminum and aligned with the barrel axis for optimal accuracy. An additional accessory rail is located beneath the air cylinder.

Magazine – Rotary-style magazine holding between 14 and 10 pellets, depending on caliber. Reloading is performed via a biathlon-style side lever, which cocks the hammer, rotates the magazine, and chambers the next pellet. Includes two magazines and a Single Shot Tray (Single Shot Adapter) for precision shooting without risking pellet deformation by the magazine mechanism.

Trigger & Safety – Manual cross-bolt safety located above the grip, preventing unintentional discharge. The adjustable trigger allows for a personalized setup to achieve maximum shooting concentration and control.
