I purchased my MP15-ORC and a pre-ban Colt AR-15A2 Sporter before I found the MP15-22. My first time shooting was with a friend who happens to be an AR nut and just happens to work for Colt in a very AR intensive position...

In fact, my avatar is a picture of my first range visit shooting one of his Colt AR's. I turned his obsession into mine.... I think I have like 7-8 various brand and model AR's. There is so much you can do with them. They remind me of Harleys, you build them to suit your needs and for your own enjoyment. There are just so many options available. Here's a quickie pic of most of them, from lt to rt... MP15-22, MP15-ORC, PWA lower\custom Colt upper, Colt pre-ban, Eagle Arms pre-ban, Colt AR15-9mm, custom upper on the floor.
