I've installed this BCG on my new 300 Blackout UBAR2 AR-15 pistol build, and it works great right out of the box! It looks good with the PSR logo too! Highly recommended!

Besides the fantastic customer support from B.A.D and fast shipping this BCG is top notch. If it's good for PSR it's good for me. Will be back for more.
Bought this and it came in the mail 2 days before a range day, took the bolt carrier apart to lubricate it and everything looks good, tested it out in 11 degree Fahrenheit weather and works just fine, ran about 3 magazines through it and so far I'm happy with the purchase, took it home to give it a good clean and everything seems to be fine after a few mags. My friends also love the print shoot repeat logo on the bolt carrier as well.
