Hand Guard Grip

While the overall quality of the handle is good, the set screw doesn't seat well.

The handle wouldn't lock down at all on my Piccatinny rail of the fore grip of my rifle. I took it apart and ended up cutting away some aluminum material on a lathe in order to get the part to fit. After I removed about 1/8" it tightened up fine! The material I removed was off of the knurled nut area shoulder facing up towards the smaller 1/2" section where it would engage the rail. Someone mentioned grind down the bottom of the grip, but the problem is the threaded portion of the plastic part of the grip needed to be 1/8" deeper. So I can't see how that would have helped unless they just muscled the aluminum part up and made their own threads? I thought of doing that, but didn't want the plastic part to split over time. Another fix would be to add a washer on top of the post section where it would engage the rail and not use the shoulder to fit in one of the cross slots. YMMV - it was cheaper for me to modify it rather than buy a much more $$ handle. I'm not even sure if I like it on since I haven't shot with it installed yet.

and both times it would not lock up to my standard 1913 picatinny UTG quad rail. All other grip products, lights, scopes, work fine. But this grip would not tighten down all the way. I wish it had, it is made well, and for about 14 bucks, it WOULD be a bargain if it fit.

Very sturdy grip, solidly made. Mine did not quite tighten all the way but this was easily fixed by removing a small amount of material from the bottom end. The grip now locks up well and could not be more sturdy.
