Strike AR-15 Gas Tube Pistol Length 6.75" 304 Stainless Steel Silver

The Strike AR-15 Gas Tube is a pistol length replacement tube for AR-15 and M-16 upper receivers, machined from 304 stainless steel and finished in a clean silver. At 6.75" overall length, it is the standard tube for pistol-length gas system builds and is a common fit for short-barrel rifles, AR pistols, and 300 Blackout uppers where lower gas system pressure is desired.

In a direct-impingement AR-15, the gas tube is the conduit between the barrel's gas port and the bolt carrier group, routing hot propellant gas to cycle the action. Strike machines this tube from 304 stainless steel for corrosion resistance and dimensional consistency, with a silver finish that stands up to the heat and fouling of repeated firing. The 6.75" length matches the pistol gas system and pairs with a pistol-length gas block.

Installation is straightforward: the gas tube seats through the gas block, indexes into the barrel's gas port journal, and is retained in the upper receiver with a 0.312" x 0.081" roll pin (included). Whether you are replacing a damaged tube, upgrading from a black nitride or parkerized finish, or completing a custom pistol-length build, this Strike gas tube delivers a precise, long-lasting fit for the AR-15 platform.
