"I bought this rail kit for my AGM M16A4, and not only has it dramatically enhanced the look of my rifle, it adds a level of '' tacticalness''. This is a great rail kit that works great. I would give 5 stars, but there were no instructions. You must remove four screws and a metal piece from the barrel nut, and put the two longer screws through two of the holes to line it up with the actual rails, all while the barrel nut is inside the metal ring the rails screw onto.
-Nice trademark on top of rails
Overall a great rail kit, go and get yourself one!"
