CMMG Banshee Upper Receiver Group 5.7x28mm 5" Barrel Black

CMMG delivers the goods with this 5.7x28 Complete Banshee Upper Receiver group. This complete upper assembly is designed to be compatible with standard AR-15/CMMG Mk4 lower receivers (when used in conjunction with 5.7 AR Conversion magazines) as well as CMMG's Mk57 lower receivers which use FN Five-seveN pattern magazines. This particular upper receiver features a 5" threaded barrel and the CMMG EML4 M-LOK Free Float Hand Guard. A bolt carrier group is included, as is the CMMG Zeroed ambidextrous charging handle, as well as a CMMG Zeroed Linear Compensator. This upper makes use of CMMG's Radial Delayed Blowback system, which delivers a softer recoil impulse and reduced bolt weight compared to the straight blowback systems seen in most pistol caliber carbines. This item is intended to be installed on either a dedicated pistol lower or a registered Short Barreled Rifle lower with proper approved ATF paperwork and Tax stamp. ALL NFA RULES APPLY.
