Never ordered a Lead & Steel product before, and am happy to say, that the quality looks very good, only range time will tell, but so far its very nicely produced.

Purchased this bcg for a 10.5in build. Coating is even and tolerances are tight. Works like a charm. Great value.

Cant beat this bolt carrier for the money. The nitride finish looks great and it’s super slick. After 1k rounds, the carrier still looks and feels new. I have not experienced a single malfunction and I have 4 in different length rifles. Staking is perfect and gas rings stay tight. Great all around bolt carrier and I will be buying more as back ups.
