Sons of Liberty Gun Works V2 gas block in .750 is a buy again product. Steel construction with even phosphate finish. Set screws thread cleanly. Aligns with the gas tube without any fitting. Solid budget gas block from a quality maker.
Sons of Liberty Gun Works V2 gas block in .750 is well machined steel. Set screws thread cleanly into the body. Wish the package included spare set screws since they can strip with overtightening. Otherwise solid block.
