I have an MP5 PDW with a Socom silencer on it... looks really cool...
as for gear... I have Woodlands and a black mesh crossdraw tactical vest.
I can look around to see if I can find a hand gun I can borrow or rent.
I'd be interested if that is good enough for ya... but I don't think I'm gonna go buy anything just for this... I've worked in the movie business before so I know how it works generally.
