The CMMG BANSHEE MK17 is an AR-style pistol built around the Mk17 platform for use with Sig Sauer P320 magazines. It uses a radial delayed blowback operating system and includes CMMG ZEROED components such as an ambidextrous charging handle, linear compensator, and a ZEROED single-stage trigger. For an optic that pairs well under $1,000, consider a compact red-dot such as the Vortex Venom to keep a low profile and maintain fast target acquisition.
Suggested applications include recreational range shooting and pistol-caliber carbine (PCC) competition use, where magazine commonality and modular AR-style controls are advantages.

The BANSHEE MK17 balances AR-style ergonomics with pistol-caliber simplicity. Its M-LOK-equipped EML7 handguard and full-length top rail give room for lights, irons, or a compact red-dot, while the RipBrace provides a stable cheek weld without obligating a folding stock. If you want an AR pistol that accepts P320 magazines and emphasizes modularity and parts commonality, the MK17 configuration is purpose-built for those priorities.
