Yankee hill machine low profile gas block with set screw mounting - Yankee Hill Machine Low Profile Gas Block With Set Screw Mounting YHM-9383

I purchased this gas block in conjunction with Mounting a Slim Front Handguard. The fit on my barrel was snug and required tapping in place. After shooting over 200 rounds there was no perceived gas leak around the block. The mounting screws supplied with the unit fit tight but I added a drop of blue Loctite to each. I had removed a fixed front sight and had to use the gas tube stop pin from that sight for this Block. If you are building a barrel from scratch you will have to buy this pin as it is not shipped with the unit.
