Built a 5 inch 7.62x39 was having trouble getting even one magazine to run without a malfunction put this on adjusted it she runs like a champ paired with a zero fail bcg it has made it a very solid dependable pistol after running close to 400 round no issues at all love this gas block and I will recommend for anyone I will be buying another one for my 7.5 300 blackout don’t wait just buy it watch a yt video set it and leave it

Bought for a AR10 build in 308 that had a gas problem with a different gas system. Adjusted to 19 clicks and the gun cycles flawlessly now. Great product all around and now dont have to remove the hand guard to adjust it. Came with the allen tool and has a t15 or t20 on the other side of it and worked great for mounting the scope mount I have. 10/10

I purchased this gas block around a year ago and have had endless problems out of it. I though maybe I didn't know what I was doing but I must have just gotten a bad copy. After tuning to my rifle and achieving a good felt recoil, the gas block still seems inconsistent for locking the bolt back even when fully open. I'm going to a standard block to alleviate the margin of error. Seems like a great concept, it just simply will not function on my build correctly at any setting.

I have installed many of these and to date haven’t had any issues with any of them. These gas blocks have a ton of adjustment in them, no matter what combo of barrel, silencer, etc., you can get it dialed in perfectly! Using the bleed off mode is fantastic, and I have never had one seize up on me. Nothing fancy, they just plain work. Buy it!

Install was smooth, adjusting went smooth, recoil is smooth, transaction was smooth. Love it

low profile and adjustable. dont think just buy!

Tuning: Leave your hand-guard off but put on the muzzle device you want to use. It's a pain to use the long hex. Start with it closed: clockwise when looking into the barrel. Turn it 4 1/2 full turns counter clock wise and confirm that the bolt does not stay open by firing one round on an empty mag. If the bolt opened, you are probably not into the bleed off yet, turn a little more. Once in bleed off mode and bolt does not open, turn 8 clicks more counter clockwise. Test again; the bolt should stay open. If it doesn't, add more clicks until is stays open. If it did stay open at 8 clicks then go back clockwise 4 clicks and test. If it still stays open, go back another 2 clicks and test. This method of finding where it does cycle and where it doesn't, then cutting the number of clicks in half is mathematically the fastest way. I use the Precision Armament M41 with this block and it shoots very soft.

I purchased this for a Micro AR build (5" barrel) to be able to adjust the gas correctly on such a short length. Instructions are straight forward and easy to follow with included extended length Allen wrench. Already over 1000 rounds with the AR after adjusting gas and have had zero issues. I'll be purchasing another one for my Grendel build.

Got this to replace the POF dictator witch didn't work, the POF dictator was send back and said to have been repaired but still didn't work. installed this and the gun worked perfectly with no problems. easy install and adjustment, high quality.
