Looks great!!!! - UTG Pro AR15 High Pro Quad-rail Gas Block for .75in Barrel

Easy to install, make sure to have the gas tube inserted properly before you drive in your retaining pin. Comes with two side lock screws to fasten it to the barrel and one set screw that’s drove in from the top, which in my opinion is smart manufacturing on the designers part. The top picatinny rail seems to be just a hair higher than the receivers picatinny rail but it’s not a drastic difference, lines up pretty good and straight. There’s a spot on the bottom that is cut out and lines up with a dimpled barrels lower set screw dimple if you have a dimpled barrel.
