i live in a town called harrah its about 20 minutes outside of okc, i used to live in colorado springs, and i was a member to the isaac walton shooting range, my dad who lives here in oklahoma used to be a class 3 arms dealer, so i have quite a few rifles and such but i recently purchased my xm15 and i really don't know a great deal about it, but i am quite a proficiant shooter, i have gotten first place and several local shooting compatitions, my favorite caliber is 22-250, i have a rem 700 bdl custom deluxe. some one mentioned about a red dot scope what some opinions about them, i prefer leupold scopes but i dont have the funds right now to spend on one. i do know from one of my best friends " ex force recon marine 2 tours in iraq'' he told me if you zero the ar15 in at 30 yards its pretty much the same at 300, so i want something that will really reach out there but at a decent price. all my optics right now are leupold, burris, and springfield, but they for what i want are out of my price range. so any info would be greatly apprietiated, and i still have family in springs and i get there about once or twice a year , oh and i am a IBEW electrician, 100% Union 100% American.....
