CMMG Mk57 Banshee Zeroed Trigger Pistol Extension 5.7x28mm FN Titanium Frame

Description

Product Overview

The CMMG Mk57 Banshee lower group combines a Zeroed Trigger with a pistol extension and titanium finish for a 5.7x28mm FN-based build. Designed for compatibility with FN Five-seveN pattern magazines, this lower group provides the serialized foundation for a compatible upper assembly and includes an ambidextrous selector safety. It is supplied as a lower group rather than a complete firearm, so a compatible upper, barrel, sights, and magazine are required for a complete build.
