I know its not LR but I had bought it off a ex-marine from my area to put on my AR-15 and no longer have the AR any longer. The buyer of my AR didn't want the Eotech when I solid it him so i kept it. It has about 500 rounds past it my via my ex-marine buddy. If you would like pictures. Contact me. I never got a change to use it myself. Just installed it and sat. I just want what i got into it. I don't plan to own any more AR-15's so im letting it go. I would like $250+shipping.
