Stay the f*** away from S7 tool steel bolts.

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.
