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.
FANTASTIC GAS BLOCK!

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.
