I just got back from the range firing this 5.56 mm ar-15. I was shooting at a 14-inch plate from 100 yards and hitting it nearly every round using the iron sights. This is the 20-inch Panther Classic DMPS. It has a non-removable carry handle and is plain barebones and naked AR-15, but fun as Hell regardless. Doesn't have the chromed line barrel, but it works without a hiccup.
Anyone else have one of these things? Won't win you any AR-15 beauty pageants, but I love mine. I also have a SW MP15x with the bells and whistles and enjoy shooting the DMPS just as much.
