CMMG Mk4 Zeroed Banshee Features The CMMG Mk4 Zeroed Banshee runs a direct impingement gas system through a 6.5 chrome moly steel barrel finished in black nitride with a 1:7 twist rate optimized for stabilizing heavier .300 AAC Blackout projectiles. Its included Zeroed 30 suppressor threads onto the 5/8x24 muzzle and tucks inside the oversized 10 M-LOK handguard which accepts suppressors up to 1.5 in diameter for a remarkably compact quiet package. The Mk4 billet 6061-T6 upper and forged 7075-T6 lower receivers are machined for a tight reliable fit and both are finished in a durable black Armor Cerakote coating. CMMG s Zeroed drop-in single stage trigger provides a crisp consistent break that improves precision over typical mil-spec triggers. Every control on the Zeroed Banshee is fully ambidextrous including the charging handle the 60/90 degree safety selector and the Zeroed pistol grip giving left and right handed shooters identical operation. The CMMG RipBrace folding system paired with a FASTBACK six-position receiver extension lets shooters adjust length of pull for stability while keeping the overall package compact and maneuverable. Feeding from a 30-round Magpul PMAG the pistol offers ample capacity for training and defensive use alike. At 6.1 lbs and backed by CMMG s Lifetime Quality Guarantee against material and workmanship defects the Zeroed Banshee is available for sale at GrabAGun for shooters wanting a suppressed-ready fully ambidextrous .300 Blackout pistol.
