Hey guys welcome to another episode of InRange and the continuing Saga of mud testing. We have an AR-15
US GI aluminum magazine with a green follower you can't see that, but it's a standard US GI magazine
This is a BCM upper it happens to have a quad rail on it
But it's a quality BCM upper, a spikes tactical bolt carrier group and a GWACS lower with a US GI trigger group
So we're going to start clean, well, clean as we can be, nothing in the gun
And we're going to fire a couple rounds to prove that it works and then we're going to move on to the mud.
You know nobody thinks an the AR-15 can pass this test.
I've... I've heard that rumor. Alright, so five rounds, ready?
On safe, I'm going to close the dust cover for the initial test. And I want to mention something. There's no rear sight here
I know there's no rear sight, before you call us an idiot. We're not shooting at a Target
This is a mud test, not an accuracy test. We ready? [yep]
[There it goes] In the mud
That's pretty good? [That's pretty nasty, let's get some on the other side.]
[That's the sign that matters] It is.
You ready? [yep. Oh yeah, pile it on.]
[Little more.]
[There we go] It's pretty soupy. [That is very soupy.] I can see stuff going into the trigger control area. [That's not good.] All right.
Here we go. [All right, hold on?] Tell me when. [Go ahead.]
Five rounds
Flawless! All right.
Dust cover's open. I'm not going to bother with that side.
We're going to put it in this way, we're going to mud it. You ready? [Let's do it again.]
[Actually, hold on, before we go any farther,]
[Let's just point out real quick, this thing actually just passed in a test that several people have told us, is]
[So insanely pointless as to be meaningless because nothing could conceivably pass it]
This just poi- has passed the test that everyone said the AK would. The AK failed. [Yeah.]
Sort of, got a C minus, C-B plus, whatever.
This just passed five rounds clean, five rounds literally submerged in goo. [All right.]
[I think we know why that is, why don't you go ahead and mud this side,]
And then uh... let's see if it keeps working before we explore why.] Alright, so we got no dust cover, the dust cover is open.
I hope that's clear on the footage. [Yep. I can see it. Oh God, now]
[I can't see it.] Literally piled it straight into the hole. [All right.]
You guys see that? I can't see it.
Let me get the rocks out of the gun. all right, there we go, ready? [Yep.] Five rounds.
Lemme keep going.
Oh my. [Oh, out of ammo.] We didn't lock open.
But the gun functioned, not one
malfunction.
Submerged in mud, dust cover closed, dust cover open, this gun summarily,
handily, beat the AK-47 in the mud test.
[Shocking.] Not shocking at all, the reason for this is that this gun is closed from the elements. Even with the dust cover open, the
tolerances around the bolt carrier group are tight enough,
that generally speaking,
debris and filth cannot get in there, unless
it is completely locked back and open. If you were to have it open like this and poured mud into it,
it'd be over.
But when it's closed, this gun is sealed.
Unlike an AK in which those tolerances are more open and therefore "more reliable" that's actually a, kind of a, load of crap
the tolerances being tighter on this gun, meant that it functioned more reliably, not less.
[The misconception people have is they think that having open space inside the gun will allow it to work dirt and mud out of the way.]
[And that might have some legitimacy in... when you're not talking about very much gunk being in there.] Yep.
[When you've got this much mud,]
[Once it gets in, you're... it's all over.] The real answer is to keep the gun seal- when it's in combat ready condition,
sealed away from the ingress of debris and filth, and the
AR-15 does an excellent job of that as we just saw how many rounds? 20 rounds, no malfunctions, literally submerged in mud.
[Fantastic.] So that being said, we're done with that.
