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 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. Limiting the gas flow means softer action and less felt recoil, allowing you to lineup follow-up shots quickly and easily.FEATURES:Allow user to adjust gas pressure from the bolt carrier without unnecessary disassemblyRadiused corners reducing sharp edgesMade in the U.S.A.SPECIFICATIONS:Material: 4140 SteelWeight: 0.78 oz.Finish: BlacknitrideCOMPATIBILITY:AR-15 and AR-10 low mass and standard mass bolt carrierINCLUDES:1x RCA Adjustable Gas Key2x Mounting Screws3x 3-1/8 Set Screws3x 2-3/16 Set Screws1x Hex Key
