I have a dpms ar 15, it has a 16" barrel and the slick side upper receiver. I put a ergo grip , intrafuse handguards and a blackhawk verticle grip on the rifle. I would trade for a nice use scope, I would realy like to try a huskemaw or a burris eliminator scope. I can email pics on request. The rifle has only been fired 10 times, and is in brand new condition.
