This is a very well built mount that fits great on my rail. I used it to mount my G2 LED Nitrolon. However, you should note that the nitrolon body seems to be a little wider than 1 inch in diameter. The mount is adjustable by spinning the open part of the mount to back out the screw a bit (if this makes sense), so the Nitrolon body will fit, but it is a pretty tight fit. Overall still looks and functions great.
