Great product but one word of warning... - Strike Industries REX - Reflex Exoskeleton

I may be slightly jaded because I like S/I products a lot and have quite a few, but I do love the fit and finish of the REX Exoskeleton. I used it to mount a Burris Fastfire 3. It was a little tricky to handle all the tiny pins and screws, but in the end it was rock solid and looks great. Even comes with some blue loctite. But one word of warning... the mounting screw that mounts the REX to the picatinny rail is small in diameter. It has a knob to tighten it with, and in the center of the knob is a allen wrench socket. DO NOT tighten with an allen wrench. I overtightened it thinking it was larger diameter and it easily broke off. However, it is competely tightened down on the R.EX Riser and will now never come off unless it loosens up on its own, but I highly doubt it will. The only reason it gets 4 stars instead of 5 is there was no warning on the instructions to not oertighten that screw.
