Key Features
- 12.50″ Medium Taper Barrel with Black Nitride Finish – The medium contour balances weight and heat dissipation, while the black nitride treatment increases surface hardness and resists fouling. This means consistent accuracy over extended strings of fire.
- EML 7″ M-LOK Handguard – Full-length M-LOK slots on three sides let you attach lights, lasers, or grips exactly where you need them. The slim profile keeps your support hand comfortable during long range sessions.
- Zeroed Parts Package – Includes a drop-in trigger, 60/90-degree ambi safety, linear compensator, Mk47 ambi charging handle, and polymer dust cover. Per CMMG, these components are matched to deliver a crisp 4.5-pound break and smooth reset.
- Coyote Tan Cerakote Receiver – The durable Cerakote finish resists scratches, chemicals, and UV exposure. It also gives the pistol a distinctive two-tone look that stands out on the range.
- 30+1 Round Capacity – Comes with a Magpul PMAG 30-round magazine, giving you ample firepower for training or defensive use. The magazine is easy to load and drop-free.
Who It’s For
This Banshee is built for families who shoot together and want a reliable pistol-caliber AR that handles .300 BLK. It’s ideal for new shooters transitioning from a rifle to a pistol platform, because the short barrel and linear compensator keep noise and recoil manageable. The ambi controls make it easy for left-handed or right-handed family members to operate safely.
Pros & Cons
- Pro: Sub-MOA accuracy with match-grade .300 BLK ammo at 100 yards (verified by CMMG spec sheet).
- Pro: Ambi safety and charging handle let you run the gun from either shoulder without changing grip.
- Con: The 12.50-inch barrel is not ideal for long-range shooting beyond 300 yards with supersonic loads—this is a close-quarters defensive tool, not a precision rifle.
