CMMG BANSHEE MK4 UPPER SUPP'D 300BLK 6.5 BLK

300BLK was practically designed to be suppressed and the ZEROED BANSHEE Mk4 Suppressed Upper Group leans into that heritage completely. - Running on Direct Impingement the 6.5 barrel pairs naturally with the included ZEROED 30 suppressor which tucks neatly inside the oversized dad bod-ish 11 M-LOK handguard. - Compatible with standard Mk4/AR15 lower receivers this upper group is the easiest way to turn any Mk4 lower into a purpose-built suppressed .300 BLK platform. - Specifications - Platform Mk4 - Caliber .300 BLK - Operating System Direct Impingement - Barrel Length 6.5 - Barrel Twist 1:07 - Barrel Contour MT - Barrel Material 4140CM Nitride - Muzzle Device ZEROED 30 - Muzzle Thread 5/8 x 24 - Gas Port Location Pistol - Gas Block .750 Adjustable - Upper Receiver Mk4 Billet 6061 T6 Aluminum - Hand Guard 11 M-LOK (accepts up to 1.5 diameter suppressors) - Finish Cerakote - Charging Handle CMMG ZEROED Ambi - Weight 4.3 lbs - Length 19.5
