CMMG Banshee 8" Upper 9mm with 1:10 Twist Rate and M-LOK Rail - Armor Black Upper Assembly with BCG and CH - 99B518DAB

Experience the pinnacle of 9mm AR performance with the 8 inches BANSHEE upper group from CMMG. Featuring a compact yet potent design, this 9mm upper leverages CMMG's innovative Radial Delayed Blowback (RDB) technology. This advanced system not only enhances shooting comfort with a softer recoil impulse but also allows for seamless compatibility with a variety of lower and magazine configurations. CMMG 9mm uppers are engineered to work flawlessly with standard AR-15/MK4 lowers and 9 AR conversion mags, as well as several pistol magazine lowers: MK9 (Colt-pattern mags), MKGs (Glock-pattern mags) and MK17 (Sig P320 mags). Available in a range of cerakote finishes to suit your style, all CMMG upper groups come complete with a bolt carrier group and essential Zeroed accessories, including: Zeroed AR-15 polymer dust cover, Zeroed AR-15 ambi charging handle and Zeroed linear compensator 9mm. Originally developed for their .45 ACP MKG platform, CMMG has seamlessly integrated their Radial Delayed Blowback system across their entire pistol caliber lineup. This technology not only reduces bolt weight but also optimizes performance compared to traditional straight blowback systems, ensuring reliability and accuracy in every shot.
