16.1" 5.7x28 AR-15 Complete Upper – CMMG Barrel | BCG & CH Included
Build a 5.7x28 AR-15 around a full-length 16.1" barrel with this complete upper assembly. Designed to fit a standard AR-15 lower or compatible CMMG Banshee lower, this upper combines a CMMG 5.7x28 barrel with a billet slick-side receiver and 15" free-float M-LOK handguard.
The 16.1" CMMG 5.7x28 barrel features a 1:9 twist, nitride finish and 1/2x28 muzzle threads. A mini slip-over compensator completes the muzzle configuration while maintaining a streamlined appearance.
Unlike a stripped or incomplete upper, this configuration includes the 5.7x28 BCG and charging handle, making it a complete upper assembly as listed.
