Here it is a CMMG® BANSHEE in the caliber that won two World Wars and inspired the creation of the Radial Delayed Blowback system. Like all of our .45 ACP pistols and rifles this BANSHEE is built on the MkG platform and is designed to use Glock-pattern .45 ACP magazines. – Available in a variety of cerakote finish options the BANSHEE series represents the most innovative AR pistols and SBRs available today. From the stylized receivers and EML handguards every BANSHEE is tailor-made to be the personal defense weapon you can always depend on. With full length M-LOK® slots on both sides and the bottom of the handguard as well as M-LOK between the top picatinny rail sections you’ll always have enough space for those must have accessories. – Platform MkG – Caliber .45 ACP – 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 MkG Forged 7075 T6 Aluminum – Hand Guard CMMG EML7 M-LOK – Finish Cerakote – Charging Handle CMMG ZEROED Ambi – Pistol Grip CMMG ZEROED Pistol Grip – Buffer Type H AR15 – Receiver Extension Pistol Tube – Trigger Type ZEROED Drop-In – Trigger Guard Integrated – Safety Selector CMMG ZEROED 60/90 Degree – Magazine Glock 26rd – Weight 4.8 lbs – Length 23.8
