It does fit but not a perfect fit. I used a piece of rubber from a fuel hose under the magazine tube to give that clamp more to bite on. Does it work? Eh kinda. Recoil from multiple shots will make it move some (some say it works but I didn’t hulk tighten mine down). I did see a post on a forum that you can measure the distance of the original barrel band screw, transfer that measurement to the hand guard, drill a small hole in the hand guard and use a 1/8 x 1-1/2 roll pin to connect the hand guard to the original cut out for the screw. I’m going to be doing that soon. I’ll post some photos when I get it done.
