Im sorry guys I just cant stop thinking about using a damn buffer in my saiga 5.45x39..whats worse metal to metal or metal to rubber? with rubber it seems to hit harder but it is peening so here are 2 pics the first one is after 100 rounds and the second pic is after about 400 rounds. I know i already asked this but could i maybe see some pics of your trunnions?






Thank you for your time.

Just use the buffer. Nothing any of us can say that hasn't already been said will convince you otherwise. You're the guy buffers were invented for (don't take that negatively).

I take no offense thank you for your time. I just want to preserve it but a buffer sounds stupid and doesnt make sense at all.

Seems to me that AKs of all types have been pounding the hell out of rear trunnions for more than six decades.  Let 'em run.

...ok then..i am sorry i am an ar guy flippin the script to ak's. so its all kind of new. with the amount of damage that has already been done to mine do you think it will last thousands of rounds?

Yup. Not a problem unless the rear trunion starts to get loose in the receiver, and I have never personally seen or heard of that happening.

There's a way to find out.

Ok. So better off without buffer, aaannd shoot the damn thing to my desire and be happy..I will put over 20,000 rounds down range with it in the next 2 years (hoping 5.45 ammo will still be available).

Chances are it will last for many more than you will ever put through it.

I seriously do shoot about 10k a year through each weapon. I think I will get another 5.45 ak as a backup. I think I will try an arsenal.

Every AK has some marks like that.

My most prized AK is 59 years old (its a part kit build, all original parts with matching serials).  Who knows how many tens of thousands of rounds have been down the barrel.  All the parts appear to be quite "high mileage parts."  It has the same marks in the rear trunion area (its a milled receiver, so technically here is no trunion.. but the back is the same design).

My rifle is fine.  And your rifle is fine, too.

If you shoot 10k rounds a year, just stay on top of typical gun maintenance.  In this case, replace your recoil spring every year or two.

So with urs that has thousands of rounds through it mine has 400 and our trunnions look the same? That doesn't make me feel good. I'm sorry I'm so worrisome about this I just want my 1 and only ak74 to be my Ak in 10 years or 40,000 rounds later still running. I would think if an Ak was gonna damage the rear trun rivets it would be with a buffer in it but metal on metal seems bad too.

Why don't you get a Wolff extra power spring?

I have one it seemed to help a little. Will a buffer egg out the rivet holes.

Perhaps his trunnion looks the same because the metal peened to the point it did then stopped, similarly how my trunnion looks the same as yours at 2K rounds. The amount of 'damage' to your rear trunnion is normal. If a buffer was needed I would imagine militaries around the world would have that figured out by now, as well as builders like the guys at Rifle Dynamics. Proper AK rivets are leaded rivets(The video starts where Jim is talking about rivets. James Yeager and ITS tactical both recorded parts of the build class, they are worth watching). The rivets will stretch and flex, absorbing recoil and then return to their original position.

You are overthinking this. His trunnion looked the same at thousands of rounds as it did at 400 rounds. Those wear marks were put there within the first few rounds and there they have stayed for thousands more. Do you fear that the selector scratch on an AK will eventually wear through the side of the reciever, or does it just get worn in the first few times and there it stays?

Bingo.  And nothing failed, ever.

Once the parts wear in a bit, the wear stops.  Same thing happens to the peening on the tail of the bolt carrier after it and the hammer wear in a little.

Ok well thank you all for you time.I will just run it without the buffer. Hopefully the gas block once it is dirty (the only part of the rifle i dont clean) enought it will slow down the cyclic action a bit.

Honestly I think using a buffer can potentially cause more problems than it solves. Most AK's will mark form time to time in the rear, In my experience. It had peened new, but it shouldn't get much, if any, worse of the course of time and rounds until your recoil spring is wore out. I wouldn't worry about it. That's just me

Why? It works as intended.

It is normal.

The impact area is not where you see the real damage should it occur - it will deform the rivets.
