The tale of two mute krinks.

[KERTWOOD]

Finally got around to finishing these two and thought I would share. Both are chambered in 5.45

- The Gray one is a rebuilt/modified Arsenal 104ur w/ dead air SM-S can cerakoted by @FatAlbert .

- The Black one is a 86 Russian Tula AKS-74U kit built on a matching 74ullc receiver w/ Bulgy CHF Barrel shown w/ Kestrel 556 can w/ custom threaded adapter.

Those are awesome!

Fantastic. Absolutely fantastic.

How well do these supress?

Over gassed and loud. Not a good platform to suppress but definitely takes the edge off.

 

[Hayata]

GORGEOUS!

I'm curious too, from someone personally shooting them and not on YouTube. My buddy has a factory Arsenal SBR pending and I'm trying to convince him to get a dead air wolverine. I'm curious as to how the SM-S sounds.

I have an HTA Guardian 9 (cheapest 9 Can in the world) and I just married it to my AR9 short barrel crank it down tight AF and shoot subs through it all day. Sounds great and don't care if the Can stays there forever and never sees a pistol. HTA has its place and I love mine for what it does.

Gas face for sure

I copied and pasted this from another thread where I gave insight.

The dead air PBS-1 is a low back pressure can and being so keeps the carrier speed somewhat manigable on MOST of the AK's running them but, be warned that the carrier on MOST AK hits the rear trunnion. It's simply just the way they were desigined and that's the reason for the long rear support rivet and two smaller rivets in the trunnion.

Here's a video of the AK in slow motion without dust cover. Notice the carrier striking the rear trunnion.

This is a problem when running high pressure cans like the Omega, Saker, Sandman Series and so on. The extra pressure from the can paired with the already over pressured /gassed AK is a recipe for disaster. It will absolutely beat the rear trunnion out of place.

Why is a AK over pressured you ask? It's desigined that way so that they will run in all adverse conditions.

And while I'm at it...

Why is the AK so loud when Suppressed? Again, it's desigined with loose tolerances to run in adverse conditions. This lets gasses escape from different areas throughout the rifle. On top of that, the gas tube is ported on some variants.

Why is the bore not concentric? Because the commies CHF process was not about precision, instead it was for production. They wanted to mass produce the AK as cheap as they could and as fast as they could. That's why they went to a stamped receiver from the original milled design. To cut cost and reduce steps for production.

These issues while running a can is the main reason why mfg are coming out with adjustable pistons and gas blocks. Until now we've had to Figure out ways to reduce carrier speed and chance the concentricity issue.

Surprisingly not that bad... The gasses have plenty of places to escape besides directly in the shooters face.
