Good quality railed gas block
Block has 4 angled screws that secure it to the barrel. There is a threaded hole on the underside that lines up with the "dimple" of the barrel but NO set screw was included. I bought 2 of these blocks & both are the same. Not sure why the screw is not included. That being said, the block is solid & good quality. I used one on a 7.62x39 build (16" carbine) and it functioned flawlessly & remained tight on the barrel after approx. 50 rounds. I would buy again.
