CMMG BANSHEE MKGs 40SW 5 | Armor Black

The CMMG BANSHEE MKGs is a compact AR-style pistol built on the MkGs platform and chambered in .40 S&W. It uses a radial delayed blowback operating system and accepts Glock-pattern .40 S&W magazines for straightforward compatibility. For an optic that pairs well without exceeding $1,000, consider a Trijicon MRO red dot — compact, durable, and suited to short-barrel AR pistols.

Common applications include recreational range training and compact practical shooting where legal. The design emphasizes compact handling and magazine commonality for users who value straightforward operation.
