Not too far from me is the LGS Magnum Sports, dunno if anyone caught their ad in the latest SSAA mag but they call themselves the .50BMG and high calibre specialists.
Ad says they've got Armalite AR50, Barrett M99, M95, Steyr HS (How's that going Brett?) Mcmillan TAC and Haenel RS-9s.
I'm not usually a tire kicker as I don't want to waste sales guys times but if all that is hanging on the wall I'm going for a gawk
