I bought 2, one for pistol and one for rifle. They both took some minor tweeking to index but was not a problem. Wish I had found these sooner and saved money on ones that wasn't the correct barrel diameter and didn't look integrated. Also, got a SJC 0016, SS for my Alexander Arms 17HMR. Looks much better on a spiral SS barrel than a black bird cadge. Showed off at last club rimfire match, others interested, also.
Never thought I could have so much fun with a .22 pistol built for RFPO division in USPSA Steel Challenge. I did 10 shots as fast as I could and video'd it on my phone in slow motion. It's obvious that the comp is doing its job directing all the gasses upward and minimizing recoil. The sights stay on target! It's cool to watch, fun to shoot, and looks good. I used washers to make it thread in the correct orientation on my barrel. I'm thinking about having a gunsmith actually fit it on, but not sure if it's worth the time and money.
The comp. works great on my pistol. The only reason it wasn't 5 stars is that it needs to be available in different diameters. I shoot mostly Tactical Solution's Barrels.
