I got this one a few months ago I can attach it to either of my AR's so thats a plus but I bought it because it's so frickin bright, for when you really want to light it up. I also bought the recommended Panasonic (green colored) batteries for better performance then the average CR123 batteries they are both on Amazon. A great flash light if you want Bright Brilliant light.
