Sig Sauer
The Sig Sauer AIRMCX177G2BLK is a CO2-powered air rifle built on proven tactical rifle ergonomics, delivering semi-automatic .177 caliber performance in a modern package. Chambered for standard .177 pellets, this air rifle combines accuracy and controllability with genuine rifle-like handling—ideal for shooters who want practical trigger time, small-game hunting, or backyard marksmanship practice without the noise and cost of powder-burning firearms.
The MCX GEN II features a 30-round magazine and semi-automatic action that lets you maintain target focus through rapid follow-ups. The rifled barrel delivers consistent accuracy across the optimal pellet weight range, while flip-up dual aperture peep sights keep you on target and adjust for windage and elevation. An M-LOK handguard gives you modern accessory mounting flexibility, and the redesigned buttstock houses quick-detach CO2 cartridges (88g or 90g) so swaps are fast and straightforward. The reduced-angle grip and flat-blade trigger feel familiar to tactical rifle shooters, while ambidextrous safety levers work equally well for left- and right-handed operation.
At 7.2 pounds with an overall length of 34.75 inches, the AIRMCX177G2BLK balances maneuverability with a comfortable pointability. Muzzle velocity reaches up to 545 feet per second depending on pellet weight and CO2 charge condition. The synthetic stock and tactical black finish are built for function over frills, and the low-profile recoil pad keeps shooting comfortable during extended sessions. This is air rifle shooting for people who value practical performance and genuine rifle-handling experience.
