ingram originally made the macs in powdersprings GA then they moved to texas and went under.cobray is not the same as ingram.cobray took up after the original macs(military armament corp.)went under.cobray started with the SWD(wayne daniels) made macs,which also went under and is now being marketed as fmj,leinad(daniels backwards).made in ducktown down south..the cobray website is in north dakota i think.he makes parts,very good ones.the mac design has been and is being made by lotsa manufactureres today-rpb out of georgia,nighthawk down there somewhere, and elsewhere.some of the current "macs" are assembled by distributers from parts bins from days gone by and some are made and assembled at the factory(rpb)which went back to the original closed bolt design from texas and modified it to improve function.they work quite well and have eliminated all the problems that plagued macs of the closed bolt design.open bolt designs(can get replacement parts,just not completed guns) can no longer be manufactured,they are simply too easy to make fa.the macs did see some use with military units but very limited.never really caught on.go to the website,the guys name is harvey.nice guy and hell call you back and give you the info you need on any mac.or go to macguns.com.another good website dedicated to macs.
