Unlike a gas block, the Rubber City Armory Adjustable Gas Key allows you to regulate gas pressure directly at the bolt carrier group (BCG) without any need to remove parts. The RCA Adjustable Gas Key works with two set screws, one allows you to limit the flow of gas and the other to lock-in the setting.
