I purchased the ND3 last fall and posted a lot about the cold weather problems. I took the scope mount off my rifle as it is a piece of junk. I now have it mounted on my R15 on the side via a picatinny rail and a quick release gizmo. I have a Fenix TK12 on the other side mounted. I use no other spotlights at night, just the ND3 and my Fenix. On mounting it on the side of my R15, I found to get the light at the right angle, I put a very small washer on the side opposite the end of the light to angle it just a little. Ten times better than the one that comes with it. The middle of the light (the laser field) is fading and shadowing. I have contacted the company but so far have not received any reply. Just mounting it on my scope does not work for me. I hold it in my left hand and scan while looking through my binoculars. Works very good. If I see something coming in, I can quickly mount it on my rifle, and use the laser until it gets closer then switch to my fenix. Holding my the forend in my left hand the laser is controled via a pressure switch with my finger tips, then my fenix light is control by my left thumb. I can quickly switch back and forth. With all the problems this thing has, I am glad I purchased it because I mainly hunt at night and I don't have to worry about big spot lights, etc. The cold weather problems can be minimized by wraping it with an ace bandage and keep holding it in your hand for warmth.
