£45 plus postage, was on a real steel  AR for 30 mins, lol, owner preferred a different option, for me it’s just too much for airsoft but the purists will like it.

MOE RVG Foregrip probably real ( almost certainly- came from the same source as sling loop) £15

Grey semi rigid duty belt with genuine conpbra buckle, fits up to 38” waist, probably down to 34” £10 has to be a bargain buckle costs more
