Well Made but Tight Fitting

Like others have said, the fit is a bit tight out of the box, but a plastic punch and deadblow hammer seated it in a minute or two. Solidly made and worth the price.

Nice piece

The Larue rail I purchased required an extremely low profile gas block. I found this one fit the bill perfectly. My only gripe, as others have found, is that its very tight. Had to put it in the vice and work on the inside with sandpaper for the better part of 30 min. Another gas block I tried slid right onto the same barrel with zero resistance. Overall though, very pleased
