4 Almost a 5 star Posted by DrRJP on Sep 22nd 2020

First let me say that once I got this correctly installed on my barrel, it worked great. Now, making that happen was a struggle bcause this device has to be mounted in one position only - with the top side facing up (or bottom side parallel to the floor) - for it to function properly. After trying different combinations of crush and star washers, I finally found an arrangement that worked - up until the 6th shot I fired.



The 7th shot launched the compensator downrange and one of the range monitors was able to find it on the floor near the backstop.



So, when I reassembled the compensator, I put some blue Lok-Tite on the threads to make sure it stayed put. That worked.



The reduction in recoil is amazing and made my AR pistol feel like I was shooting my 22LR rifle. Muzzle flip was also greatly reduced.. I actually bought two of these: one in unfinished stainless and the other one with the QPQ Coating as shown here. Because the threads on this is also coated, it didn't fit on my barrel in the same way as the uncoated stainless did; that is, it was about 1/4 of a turn away from having the comp be parallel with the floor..



All in all, I highly recommend it.
