Rubber City Armory Adjustable Gas Key AR-15 AR-10

Rubber City Armory Adjustable Gas Key If you are looking to build a lighter-weight competition AR-15, the lightweight bolt carrier group with an adjustable gas key from Rubber City Armory is for you. Unlike a gas block, the Rubber City Armory Adjustable Gas Key lets you regulate gas pressure directly at the bolt carrier group (BCG) without removing parts. The RCA Adjustable Gas Key uses two set screws: one limits gas flow, and the other locks in the setting. Limiting gas flow means softer action and less felt recoil, helping you line up follow-up shots quickly and easily.
