Gun bag for ......... normally can get my primary - M4, secondary L85A2 and Sniper - Bar10GSpec, plus at least 3 of my pistols.
I use an Ikea blue bag for plate carrier, MiniMav and drop leg setup, I like choice when I am playing in how I carry stuff, unless I know its going to be very up close and personal I will tend to avoid the full plate carrier, if there is lots of running or I expect to be crawling a lot I will rock the mini mav and if I'm going full Rambo the drop leg. This also takes spare clothing, layers are important, food and water and all the mags, bbs and gas etc.
I have a hard case (small alu box/briefcase) that contains all of my pyro and BFG, it doesn't normally make it to the safezone as I tend to decant what I think I need into the Ikea bag.
When I go out to the game area if I know we will be using a fixed regen I will have a small grab bag with spare mags, a stash of bbs gas and pyro that I top up from between games. In games I tend to only carry a small ziplock of bbs in a pocket.
