I felt the same way and especially when dealing with surplus kits where you are not sure of the round count and or age.

Very well said and completely agree.

Will have to check them out. If you have both let me know how they fare.

Very well said and agreed. Definitely feels like it increases the reliability of the gun.

@@TheGeekyNerd Yes sir, It will also in some cases reduce fealt recoil from slowing the bolt down slightly so it's not slamming the trunnion as hard, Another easy way of reducing recoil and slowing bolt carrier down is to cut a small groove on each side of the head of the piston, This allows some of the gas bypass the head of the piston/Doing the samething as if you were to install a adjustable KNS piston, Another thing I'll do is drill a .150 hole in the back of the piston to the center of the piston, Then I'll drill head of piston for a small 1/8thin NPT pipe plug, Then I'll drill little pipe plugs out starting with .045, .055, .065, .070 to let some of the Excess gas pressure through and around the head of the piston (Same concept as a Adjustable KNS adjustable gas piston), Start off with the .045 restrictor then keep going larger in orifice size until gun won't fully cycle the bolt carrier back, Then say if it doesn't cycle completely with say a .075, Drop down to a .060, Gun will fully cycle and recoil will be next to nothing, If you leave restictor completely out, Gun will not even recoil but bolt carrier won't move, I set both my .308 Vepr, .308 Saiga and 7.62x54R Vepr up like this with a .070 restrictor in each rifle and if I had to try and describe how light the recoil is, It's between shooting a 5.45x39 and a 7.62x39, Very low recoil and no hammering the trunnion

How are you sure this spring is increased power? Nowhere on ALG's website do they claim it is an increased power spring. Did you use a trigger pull gauge on the charging handle to confirm?

Buy milled....

Rivets don't come loose on AKs. The first thing to fail on military AKs ist the front trunnion. It breaks where the bolt locks, after about 100k rounds.

How’s your front trunion looking ? I have 5k rounds through my WBP and they recommend replacing springs every 2500 rounds I’m considering one of these but I don’t want it beating up the front trunion.

Only had it with handmade subsonic loads, but also helps with the recoil.

I had it happen with an NHN-91 with a recoil buffer installed. Made for a fun way to practice double feeds or just tapping the charging handle to get it all the way into battery

It should but you may have to adjust your gas block a few clicks. Do you have the kns piston?

Thank you.

Did you ever get a answer on this?

@@jyerse99 nope. But also KUSA is out of business and my kp9 is basically a paperweight this point hahaha

Or recoil spring as well?

Definitely, especially if of the non-braided variety.

Recoil spring would only be if it is hard hitting or failing to return to battery.

@@TheGeekyNerd thanks a lot🙏

Da comrade, but can always be better.

Please share your experience with it.

Lol ya good times. But I'll see your recoil spring and raise you installing a high energy double hook hammer spring. Those things can bite like a Rattlesnake

Several people attest to his claims

Sure it does

I too question this. I replaced the recoil spring on my WASR10 with the ALG due to the factory one seemed to be weak as it will not pick up a round when trying to chamber a round. One occasion when firing my rifle it didn't pick up the round and caused a FTF. I haven't had issues since when using the ALG spring but I fear it will beat the front trunnion

👀

But of course!

I tied in my M92PV and it didn’t work. Even with the piston closed up

You could yes and would also smooth out the gun even more.

My adjustable gas piston became unnecessary with this spring. Had to set it on no gas reduction at all to work with the ALG spring.

Room temp iq comment

Hopefully it helps, definitely helped a bit on mine.

@@TheGeekyNerd I think my AK builder drilled the gas hole too large. Without firing, there's definitely higher tension, so I'm eager to test it. If it's still over gassed, then modifying the gas piston here I go.

You have a cpl things i would debate here. First and mainly, dont use buffers on aks. I have been there and left. The buffer takes up the last space where the spring can continue to slow the travel of the carrier. The carrier will thump hard on the buffer and still work the rivets loose. The correct spring allows the carrier to slow and just touch the reciever, and still give the carrier the full run at the mag to strip rounds. I’ve debuffed two rifles and been pleasantly surprised. Secondly with the kns…. You can bypass enough gas to make them run like you suggested. Which is fine for a match or non combat rifle. But i would definitely not degass the weapon to that degree for any self defense tool. Happy shooting 👍

I just got mine and ran a few rounds and man it's one heck of a difference! Great product

Riiight, that last 1/2” is where the spring loses it’s momentum. 🙄

@@sandozman6085i need your help😭😭

@@CrazyhorseBuschMaster on what?

Shouldnt matter since its all the same spring rate and will eventually fully compress.

Optical illusion. I have three of these installed and they are symmetrical when unloaded.

It's not gonna hurt anything

I wouldn’t, I live in the cold and I try to keep my rifles as dry as possible

What are the results

@@jd646 haven't gone shooting yet but there not that expensive to not buy both.

@@eddiebauer2123 i bought the alg recoil spring for my zastava m70zpap as well. I'm waiting for it to come in

AK's and AKM's were designed to shoot steel cased ammo, not brass.

Stupidity is a hell of a drug

Is it finicky when changing ammo types?

I just answered my own question today when my gunsmith put this spring into my M92. My bolt carrier was getting stuck in the back due to the factory spring not holding much tension. Well that problem has been resolved.

Just got the M92 myself and a new spring, was gonna make a vid on it, but you beat me to it.

@@TheGeekyNerd So I went to my gunsmith again. After replacing the spring, the problem still going on. Luckily my gunsmith is a great Patriot and awesome to work with, also a huge AK fan. He figured the recoil spring rear guide is coming into contact with the bolt carrier, so he smoothed it out a bit and I believe it's good now. As for the KNS, he's back logged for 2-3 weeks but promised he will complete it, so I will keep you posted and/or perhaps even make a video when I tune it.

Exactly 💯

And if you are broke, don't buy it. I have never owned a gun that couldn't be made better with a trigger job and some new springs.

Agreed, but would say its not strong enough to mess up the front trunnion.

Well... remember that the spring is gonna be slowed down going forward and strips a new round from the magazine

Because a gun functions better when it is tuned for the ammunition you use. Factory guns are often overgassed and/or use heavy springs so that they will cycle a wide variety of bullet grains, powder amounts, and hard primers. If you want to shoot a certain brand of ammo or a certain bullet grain, improvements can be made to make the recoil impulse more appropriate for that ammo. If the bolt doesn't smack the rear of the gun so hard, you can reduce felt recoil and how much vertical rise there is. When you reduce recoil, follow up shots are faster. Also, hammer springs can be experimented with to improve trigger pull which will improve accuracy. This isn't just for competition shooters, you can become more efficient at using your self defense gun if you can improve recoil or accuracy and retain 100% reliability with your ammo.

No gun is perfect. A lot of AK's are overgassed for reliability. Running a suppressor exacerbates the problem. And guns wear out, improved FCG's come on the market and perhaps the use that is most important to you can be made better. You sound like someone afraid to work on your guns. Get educated. The AK is an easy platform to work on, even if it isn't as easy to assemble as an AR.

@@dbmail545 I always work on my own guns. But if it ain't broke, don't fix it. How many people run suppressors? I'm in California, ain't nobody running suppressors here in Cali unless your LEO, lol 🤣. We can barley get red army standard or tula ammo here.

@@megaman010391 sounds like a personal problem.

@@megaman010391 sounds like a personal problem.

I'd say if your recoil spring is needing a replacement or is from a parts kit is a solid item.

What a pansy! Afraid that if you take your FCG out, you won't be able to replace it? I have these on three guns, and would put them on two more if they were in stock.

Can you tell us why? I have an ALG in my WASR right now. Replaced the factory one due to it not picking up a round from the mag. I always have to push the bolt forward or re-rack the bolt from the rear and let it go forward to chamber a round.

Thanks for this comment. Nowhere on ALG's website do they say this is an increased power spring. Just because a spring is longer does not make it higher power.

@@coltonmuri3672 have you used the ALG spring too?

No, but I just ordered one anyway. I found a few random comments suggesting it could be higher power so I'll give it a chance. $11.50 for this beats $15 for the competition that actually claims 15% greater power. I would still trust ALG to choose quality steel and heat treatment and of course the dead section of the spring makes sense why it will last longer than a normal spring

Agreed and based on all other Geissele and ALG items definitely can't hurt.

That makes no sense. Why would a weaker spring beat up your gun more? I have them on three guns and they work fine. Especially good for taming a suppressor.
