Gas Block Review

So i looked up Cobratac instructions online and got generic instructions from a Cobratec blog which said to turn instruction screw in to start adjusting which is backe=wards from how this block worked. I know it's a pretty straightforward procedure but instructions with it would be nice, this is my first adjustable block. Looks great on the gun and was easy to dial in.

Fantasicpiecce of equipment I wouldn't shoot without onw. It's a great pice of equipment. As not all gas holes are created equal. This helps to tame the gas system without the expense of messing with springs and buffers too tune the gas system. And helps me from beating my shoulder to death when ever I break out my. 308./ creedmoor weapon.. And this worked so well on the AR10 . That II installed one on the M4. Once adjusted to the perfect brass ejection angle from not enough gas pressure, that's it.. It's now its in the sweet spot for comfortable shooting with out beating yourself gun and up. Highly recommend..

Great looking product. I haven't install yet but I noticed some burring on the side cutaway of the gas block. I have a deburr tool and shaved them off. Other than that great looking product

Very nice, it works like it should, do both screws work to decrease gas presser? I did not move them I looked and I think they are wide open right now.

Great product, great price and fast shipping.

burrs on the inside needed to be cleaned up before i could install the gas tube. gas tube would not go all the way in, until i was able to knock the burrs out.
