Lightweight gas block - Airborne Arms AR-15 Featherweight .750 Gas Block

Super light gas block and unique design. It does have a tight fit but still able to be pressed on by hand. The gas port on the block is larger than most barrel ports so if it’s slightly off centered you could still be functional. The gas block does have two set screws and the instructions highly recommend how to torque/tighten the screw and what order. The rear screw should have the Allen key a certain way and similar for the front (different end of Allen key) to avoid over torquing a screw or damaging the block.
