But it was designed to do some very specific things normie ars don't do
Shooting while full of water without grenading being a big one
As long as you don't need a bunch of proprietary or oddball tools to work on it and the gun doesn't require a mechanical engineering degree to comprehend, it's fine. QA autism is welcome in some cases imo.
Na I mean no German gun I've fucked with was too autistic
Cept maybe some weird Walther shit
Needing a screwdriver thing to get the slide of is gay as fuck
Is the main difference with the 416 that it's piston driven?
Yeah
And pistons don't get full of water and detonate the gun
Also generally overgassed as shit
For reliability
Full auto is like submachinegun fast because of that
And generally significantly harder recoiling then a normal ar
But that makes it more reliable
It's all a compromise, not like the Germans have some special sauce or anything, they just tweaked the design and changed up the compromises a bit
What happens with a regular gas system? Steam explosion in the tube?
Hydrostatic shock
Water is incompressible
When a fuck ton of gas pressure tries to compress it your gun pops
The barrel or the gas tube?
Here the hk tests
Gas tube i get but the reciever? Damn. The ejection port doesn't provide a suitable enough vent?
I think it's just the velocity/pressure of the gas my man
Like you're already in an overpressure situation because of water in the barrel
And iirc the reciever explosion was only when they fired the gun completely underwater
But I haven't watched the vid in a hot sec
Wow. I know hydrostaic shock is no joke but I though the gaping hole in the side of the receiver would provide enough of a pressure relief.
I mean it's not open all the time
And like the gas port area is gonna be full of water
And then it's getting a shit ton of pressure all at once
So it the bcg that pops, just takes the receiver with it
Because if you've got enough pressure to pop a big hunk of steel you can certainly pop a thin ass aluminum reciever
Oh right, there's a path inside the gas key to the interior of the carrier. So would the cam pin get sheared off?
That wouldnt really releave the pressure instantly
Also shearing pins is a bitch
My assumption on the mechanics of it is that you get so much pressure into the bcg all at once that it doesn't have time to cam the bolt open, and the bolt has way more pressure on it so it's harder to open, so the water just fucking bursts the bcg
Damn that h&k music video bumpin
i like how he doesnt wear safety goggles after the test
cause he knows it isnt gonna fuck up
