CMMG Banshee MK3 Pistol | 8.6 Blackout | 12.5″ | 33A030C-AB

The CMMG Banshee Mk3 is a compact AR-style pistol built on CMMG’s Mk3 (AR-10) size platform and chambered in 8.6 Blackout. It pairs a 12.5-inch nitride-treated 4140CM barrel with an 11-inch M-LOK EML handguard and a ZEROED drop-in single-stage trigger for a balance of controllability and modularity. For an optic that complements the pistol’s intended short-range and suppressed-capable performance, consider a low-power variable or red-dot such as the Vortex StrikeFire II 1-4×24 or a quality 1x red-dot — both options sit well under a $1,000 budget and retain a compact, low-profile fit.

Its combination of a nitride-treated 4140 barrel, M-LOK handguard and ZEROED components makes it well suited for short-range precision and specialized field use where a compact package and heavier bullet performance are desired. The build emphasizes straightforward function and upgradeability rather than decorative extras.
