GAS BLOCKS & GAS TUBES

AR-15 Gas Blocks & Gas Tubes

Dark Storm Industries offers AR-15 gas system components for new builds, upgrades, and custom upper receiver assemblies. The lineup includes gas tubes in pistol, carbine, mid-length, and rifle-length configurations along with .750 gas blocks for compatible AR-15 barrels.

Choose the gas tube length that matches your barrel and gas-port location, and select from DSI micro and railed gas block configurations for .750-inch gas journals. These components are designed around standard AR-platform dimensions for use with compatible AR-15 upper receiver assemblies.

Whether you are upgrading an existing upper or configuring a new AR-15 build, DSI gas system parts provide the core components needed to complete a properly configured direct-impingement gas system.
