Fit and finish is excellent, functions as promised. I haven't done any testing on the materials aside from using it as normal but as an engineer I get the sense it it made of a very tough polymer. The strap that ensures the plug stays put takes a little finagling to get it in place but you'll get it. This one I just bought is my 2nd one and I would buy more if I had the need. Buy with confidence. The color of the tan version looks like the classic "Magpul FDE"; it looks good.

A little expensive for what ir do what it is. Got Z-bolt and works more faster at moment to switch tail cap only. I Dont know almost the same thing

i really prefer these to the older Surefire ones. Mine have been great and stopped the flicker issue I had using the older system. My only complaint is the plastic “ring” that secures the SL connection will not work. I had to resort to using tape.
