m60 box mag idea

[fasterbassdrums]

i read recently that alot of soldiers in vietnam would braze a c-ration can to the side of their m60s so the rounds would feed in at the proper angle.

heres my idea.
wondering if it would be possible to make a c-ration can into an autowinding box mag so that you wouldn't have a gay looking box thing on the side of your gun.

scroll down and you will see that it is just used as a guide, not to hold the ammo. This is all i found

he knows that, you would have the fake bullet chain sitting over it, but the BBs would feed from the can, thats how the box mag feeds as well, fake bullets up top but the BBs go in the side of the gun from the bottom of the mag, just try to frankenstein hte box mag internals into a ration can, see if it fits, it should
