CMMG BANSHEE MK4 22LR with a 4.5-inch barrel in Armor Black. Dedicated .22 LR platform built on the Mk4 configuration for economical range use and training.
The CMMG BANSHEE MK4 is a compact, dedicated .22 LR AR-platform pistol built on the Mk4 configuration. At a 4.5-inch barrel length it is the shortest barrel offered on any CMMG AR, aimed at economical range work and training. The rifle-pattern controls and AR ergonomics make it useful for low-cost practice and casual target shooting.
Recommended optic: a Vortex Venom 3 MOA red dot (priced under $1,000) provides a fast, low-profile aiming solution that complements the BANSHEE’s compact footprint.
Typical applications include recreational plinking and dry-fire/skill retention training with reduced ammunition costs compared to centerfire calibers.

The BANSHEE MK4 22LR condenses AR ergonomics into an economical, low-recoil platform ideal for high-volume dry-fire practice, low-cost range sessions, and basic marksmanship drills. Its AR-style controls, familiar stock/brace interface, and dedicated .22 LR operation make it a practical training companion that preserves many of the handling characteristics of larger centerfire ARs while using far less-expensive ammunition.
