The CMMG Banshee MK3 operates on a direct impingement system, ensuring smooth and consistent cycling. The 12.5″ barrel, with a 1:10 twist rate, is crafted from 4140CM steel and finished with Salt Bath Nitride (SBN) for enhanced durability and corrosion resistance. The barrel is threaded with a 5/8″x24 pattern and equipped with a CMMG ZEROED Linear Compensator to reduce recoil and muzzle rise.

The CMMG EML11 M-LOK Handguard offers ample space for mounting accessories, while the CMMG ZEROED Pistol Grip ensures a comfortable and secure hold. The CMMG 6 Position Fastback Extension and CMMG RipBrace allow for quick and easy adjustments, providing flexibility in various shooting scenarios.
Equipped with a ZEROED Drop-In Single Stage Trigger, the Banshee MK3 delivers a crisp and consistent trigger pull, essential for maintaining accuracy and control. The pistol includes a Picatinny rail on the receiver, facilitating the attachment of optics and other accessories. This model comes with a Magpul 20-round PMAG, ensuring you are well-prepared for any situation.
