XPB BCG Review October 15, 2018
Reviewer: Brian C from Freedom, CA United States  
Received as promised before the deliver date. BCG came in package, very clean, excellent workmanship no scratches or imperfections that my naked eyes could see. If you are reading this because you are on the fence about buying it, just buy it, you won’t regret it and it’s a hell of a fuckin price for such a great BCG. Thanks guys.

Reviewer: tyler benecke from Big Lake, MN United States  
All the YouTube reviews are legitimate.  This bolt is very smooth, even when dry. It's very high quality and the nest value out there.  I will buy these from now on.

this is such a nice BCG I think I want them in all of my AR15.
