The CMMG Banshee Mk4 Pistol 9mm 5 Bronze is a compact AR-pattern pistol designed around CMMG’s Mk4 platform and radial delayed blowback system. Its 5-inch barrel, ZEROED RBB brake, and lightweight EML4 M-LOK handguard create a controllable, soft-shooting package with modern ergonomics. Billet and forged aluminum receivers, an ambidextrous ZEROED charging handle, and B5 Systems Bravo stock round out a configuration focused on smooth handling and dependable function.

This model’s 9mm chambering, 30-round magazine, and 20.8-inch overall length make it well suited for home defense, range use, and training where a compact footprint is preferred. The integrated handstop and full-length Picatinny rail support lights, optics, and other accessories, while the ZEROED drop-in trigger and 1:10 twist barrel support consistent performance with a variety of loads. CMMG’s attention to detail and use of quality materials reflect the company’s reputation for innovative, reliable AR-pattern firearms.
