Anyone have a clue as to how hot an M14 barrel can get when uders sustained fire?
- Thread starter suprathepeg
- Start date
I fired 3 full clips on a m14s and the damn thing was hot to hold onto through the wood of the stock. I didn't dare kiss it. 
I don't know what cook off would be but, it was probably close. I don't believe it would have worked as a squad support weapon.

i guess the best thing to do is find out what temp/ammount of heat is put out by a .308 round being fired ( some factory rounds would be easiest to find this information on). the barrell wont get any hotter than that

In the cookoff test, the U. S. Army determined...
During development of the Mk 14 Mod 0, the Naval Surface Warfare Center (Crane, IN)
found that cookoff could occur in as little as 150 rounds of continuous semi-automatic fire
with a wood stock M14 on a hot sunny day. NSWC, in later testing, obtained the following temperature readings on a Mk 14 rifle fitted with a Smith Enterprise, Inc. M14DC sound
suppressor and a third generation Sage International, Ltd. M14 EBR stock:
Mk 14 rifle fired in semi-automatic mode for 160 rounds at a rate of one per second then
allowed to cool -
chamber temperature - 178 degrees Fahrenheit
gas cylinder temperature - 496 degrees Fahrenheit
sound suppressor temperature - 734 degrees Fahrenheit
cookoff - no cookoff after ten minutes
Mk 14 rifle fired in automatic mode for 200 rounds in twenty round bursts -
chamber temperature - 250 degrees Fahrenheit
gas cylinder temperature - 525 degrees Fahrenheit
sound suppressor temperature - 1,107 degrees Fahrenheit
cookoff - cookoff occurred at sixty seconds

wow, ok, good to know!
no rapid firing 200 rounds
lol

lolwas 3 full 20's in the states. m14s. after 60 rounds could BBQ meat. The fella that posted the test results - nothing surprising there. I can't imagine 200 rounds, barrel must have been ready to brand someone. never mind the surpressor.
I have gotten mine pretty damn hot before with a couple of hundred rounds. It is definitely tough to do in Canada...maybe if you had a ton of 5 rounders standing by and somebody handing them to you. But elsewhere in the world, ten normal mags will make an M14 barrel screamingly hot, even if you aren't specifically shooting as fast as you can.
But to cook off...that's usually something close to 200 degree CELCIUS, I thought!
These days you would have to be pretty wealthy to worry about it much.
