Although there may not be as much love for .40 S&W as there was a few years ago from some shooters it still stands as a favorite of many shooters and law enforcement agencies alike. With an 8 barrel there’s not an ounce of power this MkGs BANSHEE in .40 S&W leaves behind. The MkGs platform lower receivers are designed to accept small frame 9mm/.40 S&W Glock-pattern magazines. Magazines for either caliber must match the caliber the upper group being used is chambered in. – Platform MkGs – Caliber .40 S&W – Operating System Radial Delayed Blowback – Barrel Length 8 – Barrel Twist 1:16 – Barrel Contour MT – Barrel Material 4140CM SBN – Barrel Twist 1:16 – Muzzle Device CMMG ZEROED Linear Compensator – Muzzle Thread 0.578 x 28 – Upper Receiver Billet 6061 T6 Aluminum – Lower Receiver MkGs Forged 7075 T6 Aluminum – Hand Guard CMMG EML7 M-LOK – Finish Cerakote Standard – Charging Handle CMMG ZEROED Ambi – Pistol Grip CMMG ZEROED Pistol Grip – Buffer Type Carbine – Receiver Extension CMMG 6 Position Fastback Extension – Stock / Brace CMMG RipBrace – Trigger Type ZEROED Drop-In Single Stage – Trigger Guard Integrated – Safety Selector CMMG ZEROED 60/90 Degree – Magazine Glock 22rd – Weight 5.3 lbs – Length 23.8
