Product Overview
The CMMG Banshee Mk4 is an AR-pattern pistol chambered in .300 Blackout and configured for dependable performance in compact defensive and suppressed applications. Its direct-impingement operating system uses a 12.5-inch 4140CM steel barrel with a 1:7 twist, a pistol-length gas system, and a CMMG ZEROED Linear Comp mounted on 5/8x24 threads. The billet aluminum upper and forged Mk4 lower receiver provide a durable foundation for customization, while the EML11 M-LOK handguard offers broad accessory mounting space and integrates with the full-length top Picatinny rail. A ZEROED single-stage drop-in trigger, ambidextrous charging handle, 60/90-degree safety selector, ZEROED pistol grip, and RipBrace complete the compact configuration.
