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***

Most Excellent!
Built like a tank with proven materials (C158 bolt, 4340 cam pin, S7 ejector and extractor pin, 4140 extractor). The heavy golfball staking is the same style used on the Centurion sandcutter carriers. Also doesn't hurt that chrome just looks nice. A+ for this.

Heavy stake BCG
5 stars not necessarily for finish, but function. Normal machine marks where you would expect to find them. I’d consider these A++ blems (which is awesome). Smooth and tight where they need to be. If you want a beauty queen it might be a roll of the dice. If you want a work horse that specs out for a great price and super fast shipping, then grab one. Also spend the extra ten on these the staking is worth it!!!!!

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.
