Direct Impingement AK?! - the ONLY one in the world 

Hahaha, good one!

I immediately thought "Did Jim Sullivan help conceive a bastard child in the back of an 88 Yugo after getting too sauced on vodka?" - but I like yours too... 😂

One stoned, the other on vodka

If only the AR utilized a short stroke piston as this design does, it would run much cleaner. Also, no suppressor blowback in your face.

@@collina.7336 you mean like this? ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-VSCt0qp8s8s.html

No that's a major stroke I'm calling it the ak15 like the ar47

After he gets off the train.

@@jamesstewart4211 funnily enough, they’re both real firearms, and they both fire 7.62x39mm. One of them is just a 7.62 AK-12, the other is a 7.62 AR-15 using Grendel Mags loaded with .30 Soviet.

SAME!!!!

Damn skippy

Why?

@@mkultraification why not? It is functional, smooth, less front heaviness.

@@mkultraification Just cool.

PWS should set up an AR15 upper like this....(in 762×39)

​@@almaadams3631 I like PWS's system the way it is. It's the perfect setup for a suppressed AR. This short-stroke AK looks like it would be very beneficial if you wanted to set an AK up as a DMR or precision rifle.

@@boomerisadog3899 PWS has several models: The DI musket and the Brownels AR180(short stroke).You are preaching to the choir on PWS uppers, (I never bought a complete rifle) I have or still own 762×39 Mod 0, Mod 1, and at least 3 of the Mod 2( no forward assist). I can't speak to .556 models, I prefer to build and balance that calibre myself. At 55 years old ,I hear by proclaim the PWS 11" Mod 2 762×39; the best platform made for that caliber.( Don't forget a few 20rnd. Duramags)

@@almaadams3631 I always wanted to build a 7.62x39 ar but the relatively weak extractor and bolt always made me stick with ak's to run cheap steel through. How have the PWS bolts held up for you? Maybe, I'll try one out since they seem to have figured out the mags now.

@@boomerisadog3899 PWS Dwell time (unlock) prevents the harsh bolt thrust that can damage(break extractors and lugs). Having a bolt face that is true (flat) to the barrel extention also helps. Remember; ×39 cases are very tapered (cone shaped). This makes the case almost "self ejecting". .556 cases expand to the chamber to slow down dwell time. Of coarse both chamberings contract after chamber pressure ceases but rearward thrust of ×39 will always be greater. To answer your question: I have never broken a PWS lug or extractor. Let me also say Colt had the proper ×39 AR recipe back in the early 90s. .136 inch bolt depth( same as grendel) and a .125 diameter gas port. My Colt bolt never broke either. The only problem with the Colt was super dirty chamber all the time. Chinese and Russian ammo is just dirty.(Although I am super impressed with the new Barnaul load). PWS does a limited run of ×39 every fall. You may have to pre order, but I know some dealers have some left in stock this year.

He found another reason not to build rifles?...

Why do you care what Brandon thinks? He ain't a authority on AKs at all.

@@rabbidrick7533 what do you care, AK Jesus is AK Jesus.

@@stiprus_garsas The guy that has sub par companies build non spec aks and then get mad when the ak community calls him out for it then stops having that other company stop building his aks all together. Yeah I guess thats the guy you're worshipping.

@@rabbidrick7533 Unfortunately, this is true. He is admittedly a pretty funny guy, if that's any saving grace.

I think that’s one of the reasons the “piston” is so long. I was wondering how it stayed in its rails as well and when I saw that it made sense. Definitely different.

That's normal for an AK tho, considering how small the bolt is?

My AKs have never done this. I think it's probably overgassed or the recoil spring isn't strong enough. It shouldn't want to jump the rails.

@@xezekial what it is: on a normal AK the piston stays inside the tube which holds the carrier in the rails. With this design it doesn’t have that; so the rod the carrier travels on after the initial linear piston strike attempts to keep it in the rails and it’s working but it has more play than the standard piston. My guess.

Best...rails...ever

agreed. Hard slick finish so it'd slide effortlessly would make it p0rn.

this is amazing this gun laso have smoke screen launcher whenever you fire

Those qd sockets to hide the underfolder holes is clever as well.

Woah, no way, is it really? You must be really smart

@@EOTechN9ne that QD thing is my favorite part of this entire build.

It’s actually closer to true gas impingement that the ar15, like the MAS49 and the Ljungman. The stoner action that uses a gas key and actuates the bolt like a piston is more of a strange offshoot of the original DI concept.

I was going to be part of that squad, but you gave me a place to put my comment. Short stroke piston is short stroke piston, whether the gas interacts with it at the gas block or farther back, inside the receiver. This just looks more like a variation of the short stroke piston concept. I like it, though. I'd get one of these rifles if they hit the market.

@@Glock-Tec1 agree.. the gas tube could be very well be replaced by a longer piston and achieve the same result.. like on the FAL

I think what people care about most of the time is how the piston, be it a tappet here or a bolt-piston in the AR, is recessed very far back from the gas port, and so if the AR is "DI", I don't see why this couldn't be either

And I always laugh at the AR vs AK videos because all gas operated rifles are almost the same. The G3 is an orange, the AR and the AK are both apples (if you catch my metaphor).

Rifle is fine, but we can make it better, or at least fit our own taste.

He'd have a stroke! And drink even more white claw than he already does.

Its not produced by bushmaster/freedom group so there's hope. lmao

Unless they loosen import restrictions, there is little chance. They would have to produce it here so maybe a superhero team up with kalashnikov USA?

@@Leonarco333 more bring it in like the old vepr/saiga rifles and convert it back to normal here. That’s what I’ve done with veprs and it works great.

@@FreedomsLife1776 that would be awesome.

Should we tell him?

Agreed. Long stroke piston all the way baby!!!!

@@fujimi715 And if you really hate recoil, you can go through the classic Stalin route and starve the bolt carrier until it’s skeletonized.

I have never noticed a legitimate difference between A2 sight type gas blocks and hand guards and the low- pro has block and " free float" forend. Match AR15s still have "old school" set up. Sold my Colt HBAR years ago but it was a very very accurate rifle( I can't see well enough for open sights past 100yrd. anymore) AK barrel oscillation is just big bullet+thin barrel(and maybe a trunion set in stamped steel).

by your definition there is no such thing as a free float gun than.

The SVT style was there because some of those guns needed to use stripper clip reloads

But yeah this design looks neat Hope it goes well and has public interest

@@HugeCockAndBalls Blowback?

I 100% want to see Robski's opinion in this.

Most things in life aren't "needed" to be honest.

Ive seen that argument alot on the internet. I thought carbon fouling was taken care of using different cleaner burning powders. Now, firing, say old 7.62 Soviet cartridges or even some newer rounds, itd be interesting to see buildup.

@@longbow6416 Considering it's gunpowder and burning such is still going to create carbon residue regardless, fouling is still an issue in direct impingement systems to a varying level of detriment in austere conditions. With the way AR-di systems are set up it's still venting all that gas through the key, down through the bcg and right onto the back end of the bolt and into the receiver area in general. Such a pain in the butt to keep clean, piston systems are far superior in this regard. Agreed, I'd like to see the buildup and fouling after 450 rounds, 900 rounds, and 2000 rounds (and so on) with this true hybrid platform to see where it's collecting and the effects it has on the system's performance. Granted, Slovenia isn't Iraq so the environmentals are starkly different in effect/ affect, but it'll still garner some results in the fouling aspect through use alone.

@@DJTheMetalheadMercenary Oh, yeah, I understand, you got those 2 little holes on the side of the BCG to channel gas out that came through it from the gas block, tube, gas key, etc. Doing some quick (bad) math, 7.62 and 5.56 are loaded with about the same amount of powder: 1.60-1.65 grams on both. So in theory both systems should show the same amount of coating. My question is, would Tula or Red Army Standard use a 'dirtier' powder than say Federal, Blazer, or Winchester brand ammo? I know theres a bunch of variables that could only be answered by long term use of the weapon and will it be detrimental with a different cartridge using DI. Ive built 2 Bear Creek rifles using their 7.62x39 DI system but have not run them very hard so I cant say personally if they get dirtier than a 5.56 or if itll cause stoppages with extended use. Itll be a wait and see what Zïga's research comes up with.

@@longbow6416 There's a couple different designs to how the gas is directed once it's in the key atop the bcg, but most vent it straight through the key and down one larger vent onto the back of the bolt where the sealing rings (like really tiny piston rings in a car but very small and stacked on each other) catch it and actuate the bolt and bcg backwards, direct fouling. Insofar as ammo, Tula is cleaner burning than Wolf per se, but not by much as they all source their powder from the 3 different production facilities in Russia (same with RAS). The powder Winchester uses is their proprietary production powder (and burns a little dirtier than Hornady and Federal but I think that'll improve considering they operate some of the Federal production now like the Lake City plant), not sure what the other manufacturers use, but I do know Remington is pretty dirty burning powder too (save for some of their higher end match grade stuff). Certain brands and powder types will certainly foul systems up faster than others, that's a lot of trial and error testing to see what's best for your particular system though. That's pretty awesome, I bet they can eat a good amount of ammo without too many issues, again the environment plays into the results and efficacy of the system as much as the powder/ ammo being used.

you need to know the devil's stuff to better fight it

Some AK and AK-like guns used this kind of gas tube before, so it is not a blasphemy to Kalashnikov. Really novel part is a short stroke piston and bolt carrier guide as a single part.

That's what the 416/417 is.

good point

that's only true in the case of the AR-15. this and all other DI guns still have off center torque applied by the gas system. though this one appears to mitigate that by using a guide rod.

@@Xtorin_Housecat_Ohern : The Robinson Arms XCR-L & XCR-M are also gas piston rifles. Neither of which have an off set piston rod connection. There is a two slot connection for the piston rod to fit into the bolt carrier. One is an elongated oval, the other is a smaller oval. So the piston rod rides along the middle of the bolt carrier. Instead of the end. The bolt carrier cannot tilt. The XCR-L is a long stroke gas piston. The XCR-M is a short stroke gas piston. The gas piston rod has a larger diameter when compared to the AK piston rod. I think the Robinson Arms XCR series of rifles are available in Europe. I heard they are very expensive to import into Europe. There are RU-vid videos if you want to see how the XCR system works

That's the beauty, my friend, you can wail on her all night long!

Kind of like Manca??? (If you don't know who I am talking about, watch more Polaner videos)

I want to buy one now, these fkrz...

The gas tube goes directly to the front trunnion, so in terms of placement it is DI I guess, but yeah it is definitely a short stroke piston in terms of how the system works

@@HMSNeptun Direct Impingement means that the gas hits the bolt carrier and moves it. The MAS 44 is the classic example, the AR-15 takes the gas further inside the bolt carrier so it is DI with extra steps. This rifle has an annular piston around the guide rod that drives back the bolt carrier. Gas and carrier never come into contact so it is not DI. The use of a gas tube to bring the gas to a receiver mounted cylinder decouples the forces of the gas system from the barrel. The barrel is not bent forward-and-down as the piston is pushed backwards. This is the big win for this system, getting the best parts of conventional short stroke piston and DI systems in one package.

Most of the ak reliability is the operating mass so probably not as reliable

@@AVATARComander Exactly, the reliability of an AK is tied to long-stroke piston and bit of over-gassing.

@@AVATARComander fair point

No, the reliability of an AK comes from the piston system. They just got rid of the best part of an AK.

@@XDWX ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-WFOCYYGr5k0.html This is a lightweight bolt carrier from an AK and the recoil is similar to this one but it’s long stroke rather than DI.

@@XDWX actually nvm it’s a hybrid short stroke and DI system which means you still retain some AK reliability.

@@myusername3689 Yes I commented before seeing the end. Short stroke piston systems are very good as long as the bolt timing is on track.

@@XDWX yeah

Huh huh...huh huh huh... He said "stiffer"!

He only need his shot gun.

Except it doesn’t vent gas into the internals.

@@myusername3689 true but it’s mighty reminiscent

I was really hoping for just a quick "hey we took 4 shots at a hundred yards to see what it'll look like".
