Gee, my Arms Room was like the one in

You use what you are issued, unless you know your way around the supply system well enough to get want you want without getting caught.
I know of Armorers who 'embellished' M16's for certain units and certain missions with commercially bought components, and more than one SAW gunner who bought the 90 round drum as a backup to the three issued 200 round boxes.(this was before BETA-C's exsisted) Usually as long as the embellishment was to expidite the mission, CO's would turn a blind eye.
I had an M60 'on reserve' in one Arms Room, and an M249 'on reserve' in another, in case my Sgt., who was "co-issued" my rife, decided she really wanted it in a combat zone. (Thank God I never went to war with the 56th Med. - I would have 'defected' to an infantry unit...
nadeem, lemme guess, 125th SAS Regiment, right?
I had a very fun afternoon with some Marines from the Force Recon element at Twentynine Palms when they came up to our MOUT to 'play'....practicing building clearing with MP5SD's, and these, nor any other Marines I've met- did NOT suck [expletive deleted], they kicked it!
