Unreal..... mind blown. Sure, your gun overheating by a few hundred degrees? Just throw it in this puddle here and then go right back to world destruction. Fucking awesome.

That part isn't new, pretty much all actual machine guns (not full auto assault rifles/battle rifles - usually) have quick-detach barrels so you can swap for a cool(er) one - that goes back to WW1

Usually you can only do a couple hundred rounds in quick succession before you have to change - if you continue anyway, the barrel might actually start bending Even at the specified max number of rounds, it'll be hot enough that you can see a faint red glow at night...

If you have time, it's better to air cool the barrels but if you do have to water cool them, you have to submerge it like the guy does, from one end. If you just pour water on it you can bend it too, cooling one side faster than the other.

The recoil control system is impressive, though

<--- Tens of thousands of rounds out of various GPMGs

This is the predecessor, the 7.92x57mm MG42 from WW2. A slightly modernized version in 7.62 NATO is still in use in quite a few countries:


Notice the quick change barrel and straight recoil

Is it gay if this shit makes my dick hard? I thought that was cool as hell how the barrel was vaporizing the water in that little spring.

Hell, they get hot enough to light cigarettes on - literally.

The recoil system is amazing, I noted that. And I didn't know all that about the barrels (I knew about the heating up, I did not know about the cooling down).

I always figured you take any metal that is heated to a certain point and submerge in water, no matter how slowly, that it changes the physical properties of the metal and in some cases can cause warp. Guess I was wrong. I do like when he drops the one barrel off throws a new one on, and bam back to shootin.


How much does one of those go for

Submerging the barrel isn't something you should do unless you absolutely have to - as in "people on our side will die if we don't keep sustained fire downrange"... It will shorten the life of the barrel but if you have the choice between that and not hitting worth shit because the barrel is deformed from heat, you might have to in that case.

Being that it's H&K it probably has a hefty price tag and then some. Not to mention tax stamps and shit.

Also, the fun of full auto wears off in a hurry when you have to buy the ammo yourself
