Key Features
- Compact .308 Pistol Platform — The 12.5″ barrel and pistol tube stock keep the overall length short, making it easier to maneuver in tight spaces or store in a vehicle. Why it matters: you get full-power .308 ballistics in a package that’s more portable than a full-length rifle.
- Threaded Barrel for Accessories — The 12.50″ barrel is threaded (5/8×24), so you can attach muzzle brakes, suppressors, or compensators. Why it matters: reduces recoil and noise, making it more comfortable for new shooters and more effective for defense.
- Cerakote Black Finish — This durable coating resists corrosion, scratches, and wear. Why it matters: your Banshee stays looking good and performing reliably even in rough weather or heavy use.
- 20+1 Magazine Capacity — Comes with a 20-round magazine, giving you ample firepower for range sessions or home defense. Why it matters: fewer reloads mean more time shooting and less fumbling under stress.
- Modular AR-10 Platform — The Banshee accepts standard AR-10 grips, stocks, and optics. Why it matters: you can customize it to fit your hands, your shooting style, and your mission without buying proprietary parts.
Who It’s For
This pistol is for families and beginners who want a short, easy-to-handle .308 for home defense, hunting hogs or deer in brush, or plinking at the range. It’s also a great option for shooters transitioning from a 5.56 AR to a larger caliber without giving up compactness.
Pros and Cons
- Pros: Compact size, proven .308 power, Cerakote finish, threaded barrel, modular platform, reliable CMMG build quality.
- Cons: Heavier than a 5.56 pistol (approx. 7.2 lbs unloaded), and the shorter barrel reduces velocity compared to a 16″ or 20″ rifle—expect about 200-300 fps less than a full-length .308.

Frequently Asked Questions
Is the CMMG Banshee .308 pistol legal to own?
Yes, it is classified as a pistol under federal law. Always check your state and local laws regarding barrel length, overall length, and magazine capacity. We ship to all 50 states, but you are responsible for compliance.
What magazines does the Banshee .308 use?
It accepts standard AR-10 / SR-25 pattern magazines. The included 20-round magazine works reliably, and you can use aftermarket options from Magpul, Lancer, and others.
Can I attach a suppressor to the threaded barrel?
Yes, the 5/8×24 threaded barrel is suppressor-ready. Just ensure your suppressor is rated for .308 pressure and that you comply with NFA regulations.
Is this pistol accurate at 100 yards?
With quality ammunition, expect 1.5-2 MOA accuracy at 100 yards. The short barrel and pistol brace limit long-range precision, but it’s more than adequate for hunting and defense inside 300 yards.
How does the recoil compare to a 5.56 pistol?
Recoil is noticeably heavier due to the .308 cartridge, but the Banshee’s weight and gas system help manage it. New shooters should start with reduced recoil loads and practice proper stance.
