This isn't an American Military gun, it's a prototype from MetalStorm which is an Aussie Company... and in my opinion it is worthless...other than for a "friggin cool" conversation peice.... and it is that. Could you imagine, BBQ'ing out back with your buds... "Hey guys, you see that cat over there...." hehe .. "What cat?" .. "nevermind it's gone now." :brows:
The reason they only fire it in short burst is because they can't fire it for any extended period of time with out melting/warping the barrels which would then cause it to explode with that many rounds being pushed through, plus it only holds 180 rounds, so this gun would never actually shoot 1,000,000 in a minute. They just took their 5 second figure and did the math for a minute.
You would definitey have to change out some barrels long before you ever got to a million rounds.
