Selling my RIS II Rail made by Madbull. There is very slight wear from use as expected but all DD trades are in tact. All parts present (Barrel nut, base plate and screws/washers). I ran this on my TM MWS so did modify the small pin used to connect the base plate to the M4 reciever however I have put this back in the box along with my own pin I later used for a better fit in my TM MWS and also two other different sized pins for flexibility of use, this is really for an AEG. These are quite hard to get hold of and retail at around £120. Price includes P&P, if using PayPal goods and services please add 2.9% fee. Collection welcome if you happen to be local.
