Fits my M2R fine, except thats a limited edition copper one. Got this for a new Warrior Pro X, also got the green lens cap which is a must have. As is I have to buy another light or throw it in the junk drawer. Wish it was just a little bigger because the design is great.

Nylon adjustable rail block mount, aluminum piece holder is nothing i've had own or seen to grip Tac Flash Lt. (i have quite a selection) i am ordering more of these. possibly the best i have at the fraction of the price of some others that are on my surgical tools. slightly bulkier than some others, but the engineering on this makes up for that (not a worry at all) i'll see if it holds up to some mule kicks. Tough Built for sure. time and use will be the true test of mettle.

Great mount for my warrior pro to attach to my tool.

Great product to attach your flashlight awesome
