Quick Tip: Installing the KNS AK Adjustable Gas Piston

[@Th3Su8]

I cringed a little when you were drilling that rivet. The bit looked like it was going to break. It may have just been the camera angle but it seemed to be flexing a little too much. I could just see the bit breaking and then the drill with what remained of the bit going into your partners hand. Ouch...

[@myusername3689]

Somer it’s an illusion.

[@earlycuyler2295]

Thats what " working flutes" look like. It drove me nuts when i first saw it on a new cnc machine at work that let you see the bit. I was sure i was breaking something. But its just the way our brains interpret data it cant figure out. Like when a bike wheel looks like its going backwards.

[@ogsniper743]

[@HatchMaster308]

Before you even think about buying: Take your rivet out first and measure everything. Even going exactly by the chart there is no guarantee it will fit. The roll pins will be too small. So measure the size of the pin/rivet you remove and get yourself a larger roll pin. You'd think they had this all figured out by now.

[@LinenAssociate]

The roll pins are the right size. The only reason they are there is to prevent the piston from unscrewing under recoil. I don't know what your issue was but mine installed just fine on a Romanian AKM.

[@andygold]

It looked to me like the pin was too short. If he centered it in the piston body, it didn't look long enough to actually touch either side of the bolt carrier to keep it from rotating.

[@aahhronismyname8068]

For the price of this... They should just give ya multiple size diameter and length roll pins😂

[@Pest789]

I put one of these in my transferrable AK and it makes the gun actually worth a shit on full auto. The difference in recoil is amazing. Mike, I think if you put a little more gronk on that drill bit, you could have bent it a little farther :)

Just an FYI, an Arsenal SAM7R needs a larger roll pin than than the one supplied. The hole in the gas piston needs to enlarged as well to securely lock into the bolt carrier, with the supplied roll pin the piston can be twisted back and for as well as having a lot more slop than the factory piston

VEPR SUPER owners: These have a larger pin along with thermal bond. The only thing that worked for us was drilling the pin out with a 7/32 bit and then rotating it out after getting it red hot. Hopefully I save some1 out there some headache. Good luck!

[@russream3732]

It is as easy as you see in this video. I just installed the KNS piston on a Romanian PSL (yes there are different lengths pistons. Measure to ensure you get the correct piston for your AK. PSL was pretty simple to get; there is only one. But I did get one for a Bulgarian SLR107FR - I had no idea going in to the project that there was a difference in piston lengths between 16 inch Barrel length AKs or that there was a difference in length as to where the rivet was installed - now I do). I did the install by using a pointed punch to notch the rivet at the beginning, then I used a drill to make a small hole in the rivet to rest the next punch. After that, I braced the bolt carrier and hit the rivet three times with the punch and hammer, and it fell out the other side. Unscrewed the piston,...cleaned out the hole,...screwed on the KNS piston,...drove in the proved roll pin. Done. You don’t have the clean and polished rivet connection area anymore - you have a hole and a roll pin, it’s ok. But it was simple to install. Took about 10 total minutes and that’s from a guy who is slow and special. Looking forward to the range. Thanks for posting this video, it helped!!!

I got one of these for my Saiga 7.62 and OH MY GOD those pistons are a pain to remove. Had to hog out more material than I really wanted to but because of their dimpled in factory piston. Trying to get the thing out was much more work than drilling a rivet.

[@andrewanderson7402]

I just experienced something similar with my zpap m70. Although it was more so because I should have used a different size/shape punch pin, and I think I should have taken off more material with my drill before hammering. How did it turn out for you? I got mine installed, but the rollpin is just barely making contact with one of the sides

I ordered one of these from you and it will not install on my bolt carrier. the pre-drilled holes on the piston are not far enough down the threads to align with the pre-existing hole in my bolt carrier. Help

[@earlycuyler2295]

I had the same issue. Holes dont align unles there is around 1/8" ish gap between piston and bolt carrier. There are 3 options. 1- drill holes that do align. Dont use a bit you plan on using again. 2- thread it in and locktite the snot out of it, and thread in a pair of set screws in the rivet holes. 3- just leave the small gap and be done with it. Luckily most aks have enogh " wiggle room" to allow for a slightly to long piston. Ive shot my rifle in each of these configurations and had no real issues. Of course the adjustment changes if its not all the way threaded in, but still well within functionality.

[@kellyharbeson1948]

Actually, I started with mine fully open with the can attached, and closed it down until I got the gun (a VEPR 5.45 )cycling like I wanted.

[@trunkmonkey56]

Kelly Harbeson I've read that it's a more difficult installation on a Vepr than what is shown here. Is that true?

[@dbmail545]

trunkmonkey56 Not in the least. VEPR's have special needs because of their back ends and front ends. The KNS piston is exactly the same installation. That being said I recommend a drill press for the install. I sent mine in to be converted by them.

[@trunkmonkey56]

dbmail545 are you saying you sent your bolt carrier to KNS precision? Perhaps I'll do this to my Vepr. Lots of gas in the eye suppressed.

trunkmonkey56 pretty reasonable. I think they charged me $20 and return shipped it for free. Contact them and be sure they have the correct one for your gun in stock before you do.

[@russream3732]

I am going to do the same thing - start with it open (not covering any of that elongated hole area) and then gradually close it. Can’t wait to get to the range. People are saying on videos that the Recoil is also substantially lowered. Should be interesting. I just installed it on a PSL - I have the Wolverine so it should be sweet. I am getting another KNS Piston tomorrow for a SLR107FR. I have just been running the Wolverine on it and using an ALG Extra Recoil Spring to keep the carrier off the back of the receiver, but adding it and tuning it should make it pretty sweet too.

@@AmazonWebService98 so mine did have a hole on one side where you can clearly see threading and a retaining pin, but on the opposite side it’s smooth. What I did was I just used a small 1/8 drill bit for drilling metal and slowly worked my way up to the size I felt was good enough I didn’t go bigger that the existing hole. Now just so you know the manufacturer of any Ak installs the retaining pin at an angle and then welds one side shut. but your gonna want to go as straight as possible and then break the weld by putting in a “mounted vice” and I used a Milwaukee cheater wrench with a longer bar to twist it off and break the weld once broken it will slightly crush the inside thread but that’s ok because your gonna get a thread tap or dye and re thread the bolt carrier for the new piston after that is done you just install the new kns adjustable piston, line up the holes and insert the new pin in place and your done if ya need to get a hold of me later let me know and I’ll post what I used to re thread later I have to find it in my tool box

You didn't look into it far enough then, this is off their website: Yugoslavian/Zastava M92: Some of the M92 models use a round-profile gas tube that requires a 'star guide' feature behind the piston head to ensure it is guided back into the gas block. Please specify whether your factory piston has this feature so we can include a part that replicates the guide function, AGP-C-YU. The standard profile piston we ship lacks the 'star guide' and may misalign if used in a round gas tube, and the standard profile 'fluted' gas tube cannot accommodate a 'star guide'

I own a kns right now and you are right that thing blows gas straight in your face. So you’ve had success with an adjustable block? Which one are you using?

[@CAT5752]

I'm out in my garage trying to install this on a PSL today. First, it doesn't line up. Prior to swapping gas pistons you should measure the entire length of carrier/piston group and match it. Because of the fact that there are so many different variations out there of where the cross hole is drilled in the carrier, maybe you guys shouldn't drill the threaded end for the piston. Let the customer adjust the piston in his or her carrier and drill their own hole to make it 'fit' their rifle. I like the product and I really want to get it up and running, but if you have a riveted piston, this is not that easy. The pins that were supplied with mine are not for the carrier/piston connection - they look to me to be spare roll pins for the adjustable piston to me. They would need to be 1/8" longer to even come close to holding the piston in to the carrier and even then they are not the appropriate size. Second, the measurements are not the same as a PSL piston - overall length and the actual exposed part of the piston itself. I'm not a meathead, but some kind of written directions or specs for each type of piston could be included in the package that you buy. I got a decal. Which is cool (I personally like stickers) but worthless for answering any questions or helping me to understand what I'm supposed to do with this. I would rather have an instruction sheet. It's very well built and it looks like it will function flawlessly. I wish I would have known I needed a new piston rivet prior to install day. i'm not an AK builder, or I guess I would have.
