I'm one of the smallest guys out here playing airsoft, and I carry a G&P 249, spare M4 AEG mags that I can't even use, a KAC PDW + 6 gas mags, 4000 rounds, a spare box with 2500 rounds, 3L camelbak, bigass combat knife, AND my ego.
I carry more gear than most riflemen and they still have a hard time keeping up lol
The SAW gunner should be in the BEST shape
