This looks just like the E.T.G. XP-6 that I bought for $59.95 at a gun show.It fit fine on the picatinny spec rail I made for the 10-22 I use for porcupines and skunks.I put it on my XCR for night time 'yotes too, and it works OK as long as they are inside 200 yds.The flashlight will light up their eyes at 250 yds, but to see enough of them to be sure of my target they need to be closer.It is a little more compact than some of the others I have seen too, and a bunch cheaper.The batteries(2-CR-123) have lasted really well (I haven't had to replace them yet and have run the light for about 2 hrs.)If you can get one for $60 or so, you might give it a try.
I smell varmint poontang!!!
