Hey there, first post on the forum but I'm really interested in the Mac and that 10/15 upper. Would you be interested in any type of trades? I don't have any transferrables or NFA stuff, but I've got some more uncommon/high end type guns to trade if you're interested (ex. MG42 (m53) BRP semi auto with MG3 tripod, M1A in EBR chassis w/scope, scar 17s w/trijicon credo) just to name a couple. Got lots of different stuff I'd be willing to trade if youre interested. Thanks!
