CMMG Banshee 5.7X28mm 5″ Upper


Gaining more acceptance as the go to personal defense caliber for many shooters in recent years, 5.7x28mm has proven itself to be well suited for the job. With incredibly flat shooting performance and low recoil, 5.7×28 excels at closer ranges while still providing ideal penetration. Equipped with a 5” barrel, this is the most compact 5.7x28mm upper group CMMG® offers. CMMG 5.7x28mm uppers are designed to work with CMMG Mk57™ lowers or standard AR15/Mk4 lowers (when used with 5.7 AR Conversion Mags). Available in six different Cerakote finishes, all CMMG® Upper Groups come complete with bolt carrier group and ZEROED™.
