CMMG Banshee Upper Receiver Group 57B88BD-AB Caliber: 5.7x28mm, Barrel Length: 8 in, 15% Off w/ Free S&H
This Shoots So Smooth.
We have (2) 9mm uppers for AR Pistols
Wife - PSA 4 inch barrel - Nice
Mine - CMMG 5inch barrel - No Comparison between!! So Smooth & No Problems..
Mounted on Anderson AM15 Lowers
Received it quick, this CMMG upper looks great, believe it is a quality product. Haven’t shoot it yet, just temporary mark 5 stars for its appearance and quality looks. Will add more comments later.
I purchased this to go onto a Silencer Co lower with a tax stamp to make an SBR. So far I have only had 1 feed malfunction out of 1250 rounds from 4 different manufacturers. It seems like the cerakote could be a little thicker, but it still looks awe...

Great upper, plug and shoot on my ar15 lower with cmmg 9mm magazines. Great product and well worth the price. The radial delay reduced felt recoil significantly compared to direct blow back 9mm ar uppers I have shot before.
Product Info for CMMG Banshee Upper Receiver Group
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, 5.7x28 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).
