SHOT SHOW 2018: KNS Adjustable Gas System

[@MeowMeowDeathRay]

The spokesperson seems really well informed in the products they're selling and willing to go off-script. A rare thing at Shot show

[@revgregory]

Usually your smaller companies like KNS are staffed by people who are more likely to know the products from a design and usage angle. The staff at booths for the larger companies seem to be more of the marketing drone or management sort who pick themselves for the free Vegas vacation rather than the peons who actually have the knowledge to speak in depth.

[@InrangeTv]

Yep, these guys knew what they were talking about.

[@UmamiJarate]

I guess this means that if your booth gets a visit from InRange, then its worth visiting yourself.

[@dragonstormdipro1013]

It's unbelievable how the market for AKs have grown.

[@tawaitai]

Dragonstorm Dipro Best proven platform around the world=Kalshnikov.

[@ogsniper743]

Everyone should own at least 1. Super fun gun to shoot and it's also a blast to customize and work on them.

[@tannerjablowski3192]

AK is the platform of dissidents

[@jnault6441]

Finally real AK innovation. Awesome to see. Thanks

[@Liam-B]

Really need one for a Zastava M90NP. That rifle slings 5.56 brass into the next time zone.

[@lowellhouser7731]

Drop in adjustable valve for an AK? Oh, yeah that's gonna be standard on any AK I own.

[@lexedmonds9075]

It's not drop in though. You have to manually attach it to your bolt carrier, meaning you have to remove the piston you already have.

[@lowellhouser7731]

You have to tap one whole pin out? It's completely reversible? Oh, damn, I didn't know it would be so challenging.

[@juanvazquez-torres5676]

This is great I’ve been waiting For this type of system for years my PSL’s are gonna be so happy

[@gnarshread]

Well this is awesome! I'm interested to see how the product handles extended abuse but I am optimistic that these guys are on to a good thing.

[@sakelaine2953]

This was a really good interview

[@IvorMektin1701]

I wish the Galil ARM had that back in the day.

[@theredneckengineer]

Now I can say that I knew Tom before he was famous (he used to hang out at my house a lot and build guns). Great interview and cool product!

[@ChewbacaTW]

SO COOL!!! I bet this would help decrease wear in your AK too.

[@Patriotusa44]

Exactly what I was thinking. I have a Zastava NPAP and they are great AKs but can wear out quickly if you don't do something about the brutal cycling. Already ordered one and can't wait for it. X3

[@cannonlove2]

Is the bendablility so the thing doesn't jam up when the ak is doing the barrel/receiver noodle when firing? It is insane how much ak's and fals flop around in slowmo

[@razor1uk610]

I would imagine that to be a definite yes - some parts & areas of rifles (or anything else 'engineered') are designed or allowed to flex, others are tolerated to be able to flex in places, while other components and areas are required not to flex - all depends on what sort of harmonic/resonance is wanted or unwanted in that region.

[@TheBitwise]

Even without jams, I imagine unnecessary wear and/or parts breakage would be worse without those tolerances.

[@jayboston9620]

Radical...👍...& purchased.. Thanks for bringing this to the tribe.

[@4traxx]

I think you will see a shift into the ak, Just like karl said about the renaissance, In the next couple years I would not be surprised to see more options and better built aks similar to what the ar15 market is

[@nathansmith5229]

yes i want one!

[@randyallen2771]

Glad to see your coverage of this. This should take a lot of the problems out of getting the right size gas port hole in a build. Will we see you install this on one of your AKs ? Maybe to help tame the recoil on Karl's Alpha 😉 Thanks again.

[@troy9477]

Sounds like a good idea. I imagine there is a good reason why some rifles, like the FAL, havce a certain amount of adjustment in their gas system. Certainly an over-gassed rifle needs this to prolong part life and overall service life. Great video, guys. Thanks

[@Jesses001]

I never thought this possible because it is just too much darn work to make a universal system that works with most AKs. I guess someone decided to take up that challenge. Better them then me, ha. I might pick one up someday. I do not really need it for any of my AKs, but hey, maybe I get some sub sonic ammo one of my AKs does not like someday.

[@realmenshoot3085]

9x39?!?

[@FirstDagger]

Cartridge for the VSS "Vintorez" and others.

[@Lincoln_and_the_poor-boys]

en.m.wikipedia.org/wiki/9×39mm

[@Pyrosteveo]

In case you knew about the cartridge and were surprised about them mentioning it in the states, KC has been offering it commercially to Euros, and there is talk about somehow getting ammo imports (and chambered guns) to the states.

[@leonardosechi5957]

9x39 is .300 blackout for people that listen to XS Project

[@nathanbutler8240]

@@leonardosechi5957 lol how is 9mm the same 7.62mm

[@OrangeAmped]

Awesome product for sure. Even non suppressed it is useful.

[@TheSuburban15]

I think my Interarms Tantal launches cases at about 600 feet per second. Hmmm.

[@joeballengee1095]

awesome! off topic I am hoping Mark Larue begins making red dot magnifier mounts that would work with the ultra low ak/shotgun height of a low mounted aimpoint/holosun. i can’t stand the high bore offset on my ak74. Thanks Karl and Ian for everything you do. Great info.

[@sixgunsaint]

Hmm, a newer better U.S. made AK part that works? Sign me up.

[@ABowlofPho]

I can definitely see this working for folks with those new Galil Ace rifles. Many people report them to be really overgassed and in fact, suppressor would result in cycling malfunctions. This can seem like a remedy for those folks.

[@drmaudio]

Very cool. If KNS happens to see this, I wonder how you have addressed two possible issues: 1. One would think the adjustment would want to walk out. 2. It seems it would carbon up pretty quickly and make adjustment difficult.

[@comderbob]

The clicking noise when they're playing with the system appears to be from a detent that runs axially on the adjustment thread. Though I cant figure out where the detent is located. And carbon fouling can be handled with a proper coating on the parts.

[@HalcyonDefense]

The adjustment detents and their forces are radial, the recoil is axial, so the linear acceleration has no effect on the adjustment lock. If you find videos or pictures from our first prototype - you can see that we used a compression spring in the axial direction and we DID have issues with it drifting. By moving to a radial detent system, we solved that issue completely AND reduced parts count at the same time, so that worked out well. As fas as carbon goes - we ran it for 2500 rounds of that nasty yugo M67 corrosive ammo through the full auto AK WITH a suppressor without adjusting or cleaning the piston. Afterwards, it had some nasty gunk on it that seems to be unique to that ammo - but the ports were clear and functioning, and the adjustment collar moved by hand. We really tried to break this thing, worst ammo, irresponsible sustained full auto fire while suppressed, etc......the piston and the host gun just keep on chugging. The main first prototype has in excess of 4500 rounds on it so far with no physical damage, and it's not even hardened/nitrided.

[@drmaudio]

Impressive! Thanks for the reply.

[@Hostilenemy]

Is your gun running extra gassy? Have you considered taking a break from baked beans?

[@chickennuggetfavela2580]

I saw a newer wasr that had a tight piston

[@nootis4546]

Is there a benefit with this compared to an adjustable gas block? Easier install for sure but I would imagine you get more bypassing gas in your face and in the receiver

[@langanjoseph]

Looks like Ian is sporting a new inrange t-shirt, crow nation warrior, sweet 😁

[@Curtislow2]

This should qualify as an 922r part.

[@Cinn357]

It does, the gas piston is included in the parts list for determining compliance.

[@Curtislow2]

What I Thought. Thanks for reply.

[@knsprecisioninc.1751]

We are working with ATF to see if we can count as 2 922r parts, since we now have a piston and an OP-Rod.

[@keiththiha]

Brass being a projectile? Get a g3!

[@josephhomen]

PSL!!!

[@VeraceSzK]

Shit, I might have to buy a few.

[@theiviachine]

I need this. My wasr kicked the piss out of me. And shoots the brass 20+ feet.

[@dylanhealy8126]

Just ordered one for my WASR. Already have a BD2 muzzle brake, can’t wait to install this and see how she runs

[@S.A.U.1489]

What would be the advantage of this over just dropping in an extra power recoil spring to get the ak to shoot softer?

[@craigpalmer9196]

what a 2018 AK build?

[@trevormurphy7041]

I wonder if the Russians tested this out and I had an idea popped in my head why don’t you make one of them for the SKS there might be a market there maybe some kind of AKgas System replacement for the SKS

[@ABowlofPho]

Hmm......this or that adjustable gas block that Definitive Arms is testing out right now. 🤔

[@jackkrinkov9273]

Epic!!!!!

[@kevinbooth2043]

Could this be done to an sks? All I have now but I really want a ak of some kind but am hesitant to sell my Argentine mauser with full top wood grip vs later shorted 1891 model, the video games have made the prices on bolt guns go very high no crests though :(

[@BIIGtony]

Tactical hand sanitizer?

[@Bobbgeane]

Do u have one for the PSA 556?

[@0neDoomedSpaceMarine]

Nice hat.

[@billyyesreally]

Will this work for a 74u?

[@InrangeTv]

Yes.

[@Lapinmiez]

Anyone heard of this being tested with valmet/sako rk? Im really interested to try this on my rk92s but im pretty concerned about compatibility since the gas tube is differend to the standard ak.......

[@V4MPYR1055]

Do you think this eill be avalible in europe ? I feel kinda bad not having one on my ak in switzerland

[@V4MPYR1055]

Because here in europe we are dommed to wait 10 years before having new stuff like this

[@knsprecisioninc.1751]

KNS will be at IWA. We are looking for distributors and dealers in Europe now. If you know of any that you like, ask them to contact us.

[@V4MPYR1055]

KNS Precision, Inc. Sure thing

[@Tunkkis]

Where is that beret Ian is wearing from? Poland?

[@theodoreroosevelt3143]

yup

[@sethmoyer]

I could have used this when I had an AK... Ended up selling it because it was worse in every way than my SKS-M (other than having a pistol grip vs the Monte Carlo stock I guess).

[@Stout936]

Seth Moyer I opted for an SKS over a 7.62x39 AK as well. Love my old Norinco. She's over 50 years old and still smooth as glass.

[@abwillhoite]

Is that TJ from Tiger Valley in the back?

[@InrangeTv]

No.

[@abwillhoite]

InRangeTV coulda fooled me. Spitting image.

[@abwillhoite]

[@rossgreenzweig]

What is the MSRP???

[@MrDomibella]

What this for my krink!

[@Daemascus]

Well fuck me, an aftermarket PSL part.

[@kithalsted]

Damn. I don't see any way this could be done for my Mini Draco.

[@knsprecisioninc.1751]

KNS is working on that model and the Galil Ace Pistol.

[@kithalsted]

Thanks. Already cleared up via email; forgot I had put this comment here.

[@JohnnyDogs1978]

Good idea. Anything like this been done before?

[@Myhouse69420]

NoMoreYouSure1000 probably

[@JohnnyDogs1978]

Rafael Lastra com yep, I just wondered if aks had been done because they're over gassed. They'll do well with this.

[@JohnnyDogs1978]

Rafael Lastra com did he say 9×39?

[@dbmail545]

NoMoreYouSure1000 Definitive Arms is bringing an adjustable gas block/front sight. I would have liked to wait for it, but Chase hasn't even decided on a price yet.

[@user-ud2ij7ro5c]

The poor mans bleed off system is called notching the piston. A vice, grinder and a set of balls are all that is needed.....

[@TheLoveLess123]

Would this work in a PSL?

[@HalcyonDefense]

Yes, and it is one of the more dramatic changes - too bad they are not importing them anymore. This piston, a Dead Air Wolverine can, and a nice trigger really turns the PSL into something nice to shoot. We were testing the piston in our shop PSL with Winchester brass-cased 180 grain ammo with the Wolverine. It was dropping brass 6ft away, locking open on empty, and not a mark on the cases save for where they bounced off the top cover on ejection. 100% undamaged and reloadable. Bolt velocity was nice and slow, just a joy to shoot compared to factory.

[@knsprecisioninc.1751]

Yes. The PSL version is available.

[@Ratty98]

Its weird seeing a AK shoot that slow or is that just me

[@knsprecisioninc.1751]

The piston really changes the whole dynamic. The slow rate of fire is a result of the carrier coming back slower and not bouncing off the rear trunion. The felt recoil is softer, the gun is quieter, and it runs slower.

[@petesheppard1709]

When will the RAS47 and IO versions be out???

[@rcairnut]

they already have a solution for these 2, you can weld the piston into the gas tube and all will be well

[@petesheppard1709]

Recycle...get some use for the metal

[@0neDoomedSpaceMarine]

We're joking around, but I think dialing down the gas on RAS47 junker would do a lot to make it safer and not batter itself. They're more overgassed than normal and are brittle in construction. It's still a garbage rifle, but it won't break. Probably.

[@Player_Review]

For those unable to make the objectively better decision of going with an AR-15, this is a welcome entry to the 3rd world market.

[@adam-k]

So AR-s like the Toyota-s of the gun world? I wonder why dont everybody drive a Toyota.

[@jameshealy4594]

What I've learned from this comment string: Apparently, AK guys drive Chevys. Or is it Chevy drivers choose AKs.

[@adam-k]

The point I wanted to make is that 99% of people in the US, who buys AR or AK in the commercial market, is shooting their guns recreationaly and likely to have multiple guns .Performance, modularity and weather sealing, has very little to do what guns they choose, unless performance is their goal. (ie. they compete) Most people dont go to an open range when it is pouring rain and dont dump their gun in the mud.

[@sethmoyer]

Karl and Ian: "The AK is a fantastic weapons platform." Guy in the comments of a KZbin video: "The AR-15 is clearly superior, m'lady." Hmm, not sure who to believe.

[@keithlarsen7557]

They're also less sturdy, harder to clean, lack power and penetration, lack folding stock capability.

[@lexedmonds9075]

I don't like it. Zastava has an adjustable gas system on their AKs. They just insert it into the front of the gas tube so you don't have to REMOVE YOUR BOLT to adjust it. 10/10 for engineering. 0/10 for ease of use and cost.

[@johnspurlock4577]

Lex Edmonds soo punching out a pin and punching a new one in is hard? And 100$ to run your ak suppressed with less gas in your face is too much?
