Cmmg Banshee Mk17 Pistol 9mm 8 Armor Blk

The CMMG Banshee Mk17 is a 9mm pistol-caliber AR platform designed around Sig Sauer P320 magazine compatibility. If you've been running a P320 handgun and want seamless mag sharing with a short-barreled rifle platform, the Banshee Mk17 lets you do exactly that—while keeping you in full AR15 ergonomics and modularity. The 8-inch barrel and fixed ejector radial delayed blowback design deliver reliable performance in a compact, maneuverable package ideal for home defense, vehicle storage, or anyone building a cohesive 9mm ecosystem.

Build quality starts with a billet 6061 T6 aluminum upper and forged 7075 T6 aluminum lower receiver, both finished in Cerakote for durability. The CMMG EML7 handguard runs full M-LOK slots on the sides and bottom, plus M-LOK between top picatinny sections—plenty of real estate for lights, lasers, or other must-have gear. Everything wears the CMMG ZEROED brand touches: ambi charging handle, single-stage trigger, 60/90-degree safety selector, and pistol grip that feel right at home in an AR ecosystem.

Weighing 4.9 lbs and stretching 23.7 inches end-to-end, the Mk17 is genuinely portable. The CMMG RipBrace gives you rapid deployment and a stable shooting platform, while the CMMG ZEROED linear compensator tames the 1:10-twist barrel's muzzle impulse. Thread pitch is 1/2 x 28, standard for 9mm, so suppressors and muzzle devices are readily available. Accept P320 21-round mags, and you've got capacity that matches your handgun logistics.

This is a purpose-built 9mm platform that respects AR shooters' expectations: proven controls, mil-spec dimensions, and genuine customization options. Not a gimmick—a practical way to consolidate your 9mm ammo, mags, and muscle memory across rifle and pistol.
