hey everyone, thanks for having me. i just recently purchased a bushmaster xm15-es2, its got a 24" heavy stainless barrel it has a rail system for a scope but it has some kind of really cheap scope on it. I bought the rifle used at a pawn shop it is in really good condition and i only paid $750 bucks for it, i thought that was a pretty good deal, but i am not sure can anyone drop any insight on that for me, plus i want to purchase a decent scope for it something in the $100 to $150 dollar range does anyone have any insight or sugestions? thanks a lot for your time and all. and if there are any questions just hit me up.
