Appropriate for 308 caliber rifles, not 6.5 or 6 creedmor - LANTAC Enhanced Full Auto Style .308/7.62 Bolt Carrier Group (BCG)

I bought this after receiving confirmation from LANTAC that this uses a "High Pressure" firing pin. It clearly doesn't because it is cratering and, while rarely, piercing primers. When I switched to a JP EnhancedBolt in the same carrier (thankfully they both headspace), I had zero issues going forward. The firing pin on the JP is smaller. Additionally, the edges of the lugs on the JP are rounded off just a little unlike the LANTAC's bolt, which really has no fundamental difference to it than what comes in a cheap AR bolt. It has a great carrier design, though, and honestly they should just sell the carrier and let us buy a bolt from someone who actually figured out how to deal with 6.5/6 CM rifles.
