I've got 2 AR-15's so I would pick the lighter of the 2 which is my dpms. It's allready pretty well setup with a new gas block with folding front sight, magpul mbus rear sight, aimpoint red dot, magpul moe forend with a tac light and magpull stubby grip, and last an Magpull enlarged trigger guard for gloved fingers. My hagun would of course be my sig P220R SAO. I have a few hundred rounds of 45ACP and several hundered rounds of mixed 5.56. I think I have 8 or so magpull Pmags so that would fully set me up on firearms. Other than that I have a travel water purifier a stash of bic lighters and other survival equipment.
