Best BCG out there
Written on Jul 20, 2018
I got this because Krieger Barrels will only chamber to a JP bolt. The cut is different than a standard BCG: It will not let the dust cover close unless the BGC is either locked back or fully in battery. It has extra bearing surface to ride in the upper receiver. The parts move with almost no friction.

Great Bolt Carrier
Written on Jul 20, 2018
I got this because I had a JP bolt. I got the JP bolt because it's the only bolt that Krieger Barrels will head-space their barrels to. Based on what I've seen so far, I see why. The carrier is cut differently than a stock carrier. The carrier won't let the dust cover close unless the carrier is retracted (locked back) or fully in battery. It's got way more contact area than a standard bolt carrier. The JP bolt rides in there really smoothly.
