an M4 (operated by a government agent) will fire a 700+ rounds/min, but not a civilian owned AR.
a hand held weapon capable of about 12 rounds a second? What are you drinking. Damn gun would melt.
That’0s a cyclic rate of fire that assumes the weapon is belt fed and no time is taken out for magazine chan
That’s a cyclic rate of fire arrived at by taking the time it takes to empty a standard 30 round magazine on full auto, dividing it into a minute, and multiplying the result by 30. It doesn’t consider either the time for magazine changes or the totally destructive heat buildup that would occur from such a rate of fire. When training troops to use belt fed full auto machine guns, the Army trains them to fire in three shot bursts to keep from melting the guns’ barrels.
Say he had 50 round mags, that would mean 14 mag changes. It takes 10 to 15 sec per change it would take 140 sec just to change mags . So yes, using the common core math he could shoot 700 rounds a minuet!
It would be too hot to hold after 200 rounds.
The theoretical cyclic rate is that high, (775 rpm) but if you had a magazine with that many rounds and held down the trigger with the selector switch on “auto”, the generated heat might cause the barrel to soften and droop with the rounds punching thru the side of the barrel after the rifling is shot away. This weapon does not have a quick change barrel, unlike the M249 SAW, the M-60 and M-240B general purpose machine guns. Even they require a barrel change after so long on their maximum effective rates of fire.
The sustained rate of fire for the M4 carbine is rated at 15 rounds per minute. The maximum effective rate of fire is 45-65 rounds per minute for 10 minutes or so on semi-auto.
In a pinch or heavy duty firefight you may have to exceed these recommendations (as I regularly did in combat) but you risk significant damage to the rifle. They do over build them a bit to allow for these eventualities.
