The Sig Sauer MPX PCC .22 Caliber PCP Air Rifle is a semi-automatic, pre-charged pneumatic (PCP) airgun designed to replicate the look and feel of its centerfire pistol caliber carbine counterpart. It features a 13-cubic-inch (213 cc) regulated air cylinder that fills to 3,000 psi and delivers a consistent 1,100 psi output, producing over 100 shots per fill. Chambered for .22 caliber pellets, this black air rifle achieves muzzle velocities up to 700 FPS and utilizes an auto-advancing magazine system that holds an 8-round cylinder, with storage in the magazine for 3 additional spare cylinders. Constructed with a full metal receiver and polymer furniture, it comes equipped with a reduced-angle pistol grip compatible with standard AR-15 grips, an M-LOK handguard, flip-up front and rear sights, and a quick-detach adjustable buttstock for easy access to the air cylinder.
