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***

-Phosphate Extractor

-Phosphate Gas Key 

-Sprinco 5-coil Extractor Spring and Sprinco Ejector Spring

-OCKS Fasteners, Custom Staked by Hand

Microbest is one of the finest manufacturers of mil-spec bolt carrier groups for the military and small arms manufacturers. These are individually High Pressure Tested and then undergo a Magnetic Particle Inspection. We recommend degreasing and lubricating before installation. Ships in OEM packaging.
