AR-15 Gas Blocks & Tubes
AR 15 Gas Blocks & Tubes
The AR 15 Gas Block and Gas Tube are critical components in the operation of an AR 15 rifle. The gas block sits between the barrel and the gas system, controlling the flow of gas from the fired round to the bolt carrier group, which cycles the action. The gas tube routes the gas from the gas block to the bolt carrier group. At Black Rifle Depot, we offer a wide range of AR 15 Gas Blocks and Tubes from top brands in the industry, such as AERO Precision, Bravo Company, Strike Industies, and more. These components are made from high-quality materials, such as stainless steel, to ensure durability and withstand heavy use. They come in various sizes to fit different barrel diameters, and some models feature adjustable gas flow for customizable performance.
