Sharps' Xtreme Performance bolt carrier group

[scooter22]

Don't try to reinvent the wheel.. PSA was selling Toolcraft C158 nitride BCGs for 100 bucks for the last month or 2.

Enter KAC, LMT, Geissele...

Did you have any trouble with the replacement bolt Sharps sent you? How many rounds now?

Geissele & Larue triggers are both made from S7 tool steel. They have pretty good reputations. Maybe you just had a bad batch?

Bolt lugs are very different from triggers. Not to mention I bought my bolt a few years after the reports of them breaking lugs on arfcom due to improper heat treating. How many "bad batches" are they going to have I wonder. If a company cant figure it out after several years I just write them off completely.

Its in some loaner franken gun that never gets shot. Probably less than 1000 rounds. Id never put an S7 bolt in any gun Im going to depend on.

Clearly you don’t understand the difference between a bolt and a trigger.

I know the difference.
