Madbull Daniel Defense MK12 12" M4A1 RIS II Airsoft CNC Aluminum RIS

"This is well made and looks great. Only complaint is that you have to buy a G&P spec barrel nut separately and it is longer than the one that comes with it and is just too long by about 2mm so it is a bit tough to get the RIS to seat back against the ring that secures it without either modifying the nut or the corners of the RIS that touch it.

This problem will not exist for non-G&P threaded guns as the included Nut is shorter.
