So far its been great! - Sharps Rifle Company Xtreme Performance Bolt XPB Balanced Carrier Group

I own somewhere around 13-15 BCG’s. Some very expensive and others not so much. This is my second BCG from Sharps Rifle and the XPB line. I will say that the gas rings lock the bolt up tight and needs a little bit of time to break in if you have a gas system that is a little anemic or gas port. I use these in SPR’s that have 18” premium series BA fluted barrels that have .093 gas ports. The speck on your typical MK12 is .998 to .101 (or very very close without looking at crane chart. I actually had to open up the gas port on these barrels to .098 and the bolt runs excellent. Ejection is at 3’oclock with grain 77 OTM. Going to a heavier buffer to get a hair closer to 4’oclock. When you get into these rifles, the timing is everything and needs some tinkering. The blast are very smooth and the finish is very nice. I think for the money, it’s a great value. I have other nickel boron BCG’s from Spikes, Tool Craft, WMD, as well as DD and BCM. My preferred bolt is the Sharps but time will tell. My first SRC purchased in 2023 has held up very well and gets a lot of rounds through it.
