Quality and reliability - Sharps Rifle Company AR-15 Xtreme Performance Bolt XPB Carrier Group (BCG)

These are awesome products and great quality. They have the “diamond like coating”. Quality control is on point. The bolt itself is fantastic if that’s all you can afford. I put one in a Toolcraft bolt carrier. Fit and function better than the original. With the tapered lugs. Great for guns that have a couple thousand rounds in them. And you break a lug and just need the bolt. Only BCG I’ll run in my stuff from now on.
