The tactical personal defense market continues to shift toward compact, low-recoil platforms that balance controllability, capacity, and modularity. For operators and responsible citizens who prioritize maneuverability without sacrificing firepower, modern PDWs built on familiar AR ergonomics offer a compelling middle ground.
CMMG BANSHEE MK57 brings the 5.7x28mm chambering into an ultra-compact AR platform with a 5″ barrel and a host of purpose-built features. Chambered in 5.7x28mm — a round praised for lower recoil than 5.56mm at close ranges — this BANSHEE ships with a (1) 40rd capacity CMMG magazine and a 5″ barrel with 1/2×28 TPI linked to a CMMG Zeroed Linear Comp to tame muzzle rise. Built on the Mk4 – AR15 platform, it accepts a standard AR15 lower receiver and uses CMMG’s new 5.7x28mm AR conversion mags. The Mk4 forged 7075 T6 lower and billet 6061 T6 upper provide a robust, service-ready foundation, while the CMMG Ripbrace and EML4 handguard deliver practical ergonomics for quick deployment.

Performance and Ballistics
The 5.7x28mm cartridge excels at close- to intermediate-range engagements where low recoil and fast follow-up shots matter. With a 5″ barrel the MK57 sacrifices some velocity compared to longer barrels but retains the caliber’s signature controllability and flatter point-of-impact at common defensive distances. The Zeroed Linear Comp and 1/2×28 TPI threading mitigate muzzle rise and help keep shots on target during rapid strings.
Design, Controls, and Modularity
Handguard and Accessory Options
The new EML4 handguard includes M-LOK slots at 3, 6, & 9 o’clock and a full-length Picatinny top rail for optics, lights, and offsets. An integrated handstop enhances repeatable hand placement for consistent recoil management.
Receiver and Brace
Construction pairs a billet 6061 T6 upper with an MK4 forged 7075 T6 lower for a durable, tight-feeling platform. The quick-deploy Ripbrace offers stabilizing support while maintaining a compact footprint for vehicle or home carry. Magazine compatibility with CMMG’s 40rd 5.7 mags and AR conversion mag options adds logistical flexibility.
For those seeking a compact, tactical-ready PDW that leverages AR familiarity, the CMMG BANSHEE MK57 presents a purpose-built solution with thoughtful components and 5.7x28mm performance. Check current availability to confirm stock and proceed to the retailer purchase page.
