My maruzen Mac 11 is pretty much fucked and i have no idea where to start trying to figure out how to restore it to some state of functionality, besides maybe changing the seals and stuff. If i remember correctly it has a hard time holding gas in the mags and has trouble firing, but i'd have to try it out to find out fully.
It's 1am here so i'm not going to try it out right now, but any suggestions on what else i could try to improve it's functionality in general?
Also, where could i get cheaper, modern magazines compatible with it? I found somewhere selling original Maruzen magazines, but they're 40 pounds a peice.
P. much all gas SMG mags are gonna be in the $40 range. But you should go over all the seals just on principle and then check the loading nozzle and bolt assembly.
You might have to shim the routers on the tops of the mags if the loading nozzle is worn where the gas is routed into the nozzle
