I hope this isn't posted in the wrong area. I need some major help!! I am getting married in a few weeks to a great guy. He is a serious gun enthusiast. I would really like to buy him an AR 15 as a wedding present. My dilemma is that I have no idea what to buy and no idea where to buy. I recall him once saying something about the .22 conversion for an AR, correct me if I am wrong. I am not the most knowledgeable when it comes to guns. He currently owns: S&W Hammerless revolver Glock 17 NAA Magnum Mini revolver Kimber 1911 Marlin Rifle Shotgun 2 other revolvers Sorry I can't be accurate on names and calibers. I really am looking to find out what I should be looking for in a decent AR. Any help would be appreciated. Thank you!
