The CMMG Banshee MK4 in .300 Blackout is a compact AR15-pattern rifle engineered for this intermediate cartridge. The 12.50″ medium taper threaded barrel is finished in black nitride, paired with a black Armor Cerakote aluminum receiver featuring Picatinny rail mounting.
The EML 7″ handguard offers extensive modularity with full-length M-LOK slots on both sides, the bottom, and between the top Picatinny rail sections. The rifle ships with CMMG ZEROED components throughout: pistol grip, drop-in trigger, 60/90 degree ambi safety, linear compensator for .308 Win, Mk47 ambi charging handle, and AR15 polymer dust cover.
A 30-round capacity Magpul magazine is included. The .300 Blackout cartridge delivers its intended performance in the AR15-pattern platform that is the CMMG Mk4.
