Product Info for CMMG 5.7X28mm 5in Banshee Upper Group Receiver

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.

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).image
