Makes Dimpling Extremely Easy and Accurate
A great tool, very easy to use and accurate. You do have to be careful that you're tightening the alignment set screw into the gas port and not a random spot on the barrel, but that's all it takes to get perfect alignment. Once it's aligned and tightened, it's very secure on the barrel. The drill guide screw does seem to be hardened a bit, I didn't notice it getting chewed up from the drill bit, so it should last for multiple uses. The only thing I would have preferred is that it come with the appropriate drill bit. Overall a great item, and I was able to install the gas block on my nitrided barrel perfectly.
