    Nothing too fancy here folks. Just a solid adjustable block. The finish is good, fitment spot on and works as described. Put this on a new build with a 16″ Ballistic Advantage (midlength) with the adjustment screw in about middle. first few shots yielded FTE, FTF. Gave a bit more gas, problems solved. Took off one star because the block arrived missing the locking set screw. (supposed to be 2, one adjusts, the other locks it down.) I have one, so I didn’t have to wait around. It happens. I still would buy another.

    Works as advertised. Solid, well made. Love the fact that they sell them assembled with a gas tube. That’s one job I’ll leave to the pros.

    One other thing that I can’t stress enough is that these gas blocks are low profile, and will fit under most slim handguards in ways that other gas blocks will not (I’m looking at you, JP).

    Worked great adjusted to about 2 turns out and adjusted from there . Gun cycling good was over gassed badly from factory. I wish it came with a long Allen wrench to adjust it . I had to make a wrench to adjust under the hand guard

    Great assembly , Went together not an issue, the price is cheaper for this than buying just a gas block . 5 STAR
