Description
Limited Edition
These are the same BCGs as our Premium Chrome, but we went one step farther. Instead of the factory staking that most of our BCGs receive, we asked our fellow San Antonio AR-tist (did we just coin that term?) Phillip Kimm of Bexar Arms to give them a heavy duty stake. If the first thing you do is check the gas key for a superior stake, this BCG is for you.
These are designed to last. Each gas key is meticulously staked by hand with OCKS premium carrier key screws and individually checked for optimum alignment.
***These are All-Chrome Except for Phosphate Gas Key and Extractor***

Microbest Chromed Super Stake
“Review Rating” was supposed to be 5 out 5 stars. Hopefully I have corrected that!

Microbest Chrome BCG w/OCKS
Chromed, OCKS, proper staking, phosphate gas key and ejector, Sprinco springs. Checks all the boxes. Don’t own gauges yet to test 3 bore, but passes naked eye visual. At this pricepoint hard to beat. Customer service was Great, a human answered and was willing to talk about their product offering.
