The low profile Adjustable gas block for .750 diameter barrel is constructed of 1141 high strength steel with a magnesium Phosphate finish. Gas block #8-32 adjustment set screw. The gas block held in place by 2 10-32 set screws. The block is 1.38in tall 1in in length and is .625in from bore center to gas tube. It is .920 in width and comes with a roll pin. From the back of the gas block to the gas port hole is .250. This leaves .035 between the back of the gas block and most steps in the barrel. This is for installing of the A2 style hand guards. So there should be a .035 gap between the barrel step and the gas block. This can be filled with spacer or leave empty.

Well made and packaged, mounted very easy and fit excellent, even unpinned it had zero play and took a bit of force (no tools) to turn, held place easy and fit a standard bench block well when pinning and setting the screws. It came fully closed, and has infinite adjustability…but tuned so easy, I will never use an adjustable block with detents again (I don't use suppressors, FYI), you can count on it alone to get the gas right and don't have to fidget with ports, springs or buffers…Highly recommended. The only other thing I can say is the adjustment is on the left side of the gun, not a big issue, but I would've preferred it be on the front or at least on the right as it requires me to remove my rail as the rail slots don't line up with the adjustment screw.
