Recoil Buffer

This has been asked before I'm sure but does a recoil buffer really help? I have one shaped like a H and thought I'd at least try it.

I got my ears pinned back on this one. Seems that there is supposed to be some space left when the bolt comes back. If it hits, that means you need a new spring. I had a buffer, but couldn't tell if it was getting hit so I took mine out and put a piece of masking tape in there. I haven't had a chance to shoot it yet to see if the bolt hits the tape. Some smart ass said to stick your friends finger in there and he would tell you if it hits. ho,ho.
Aftermarket buffers are designed to separate fools from their money.

In some guns, they cause receiver destruction.

As partsman indicates, the AK is designed so that the recoil spring stops the rearward travel of the bolt carrier just shy of the rear block. If you're having contact between them, you most likely need a new recoil spring (or have other issues that need looking at).

P.S. A search of the forum will bring up lots on this subject.
The carrier should stop 3 -5 mm before contact with the stock block.
The recoil spring AND the hammer/trigger spring together provide resistance to the rearward movement of the carrier.
If the carrier is striking the block hard, BOTH should be checked. If either/both is (are) weak, that's the most likely cause.
I put buffers in most of my AK's.
Also, I've got a Galil .223 (AK) that I put a South African made buffer in and it makes the gun noticeably smoother.

10/22's will run smoother with a buffer pin in place of the metal rod as well, ask the guys at rimfirecentral (you know - the ones that can shoot the staples out of your target at the range :naughty:).

But there are some types of after market buffers that can do more damage than good, just depends on the gun and type of buffer.
It can smooth out some AK's.
It depends really.
I tried one in my PSL.....and I was getting double taps on one pull.
Go figure. I took it out.
I have one in my 8mm RPK conversion, and it is a real asset in calming recoil.
Experience is the best teacher.
I think theyre a bad idea because I heard on the internet they are a bad idea. I have never known of anyone that had one damaged or have I seen one that has been damaged by using one.

Life is full of such controversies.
I use them when shooting hand loads that are hotter then factory but there not nessacary on factory ammo. if you do get one get a thin soft one. I think of those as a over load spring. tha bullet is out the barrel before the carreier bottoms out so how they are susposed to improve accuracy is a mystery to me.
Yes do search - more controversy than actual facts on them! Gunco has its own built-in search feature too BTW: :)

I'll add to the discussion that a buffer is a good way to fix rails that were cut too much that cause the carrier to jump off the rails. I think every home builder has made that mistake at least once - I know I did :) This is the best reason I've found to use one. I have not experienced huge benefits in the recoil reduction department, which of course is anecdotal - it "felt" better but how do you measure that? Other rifles have them built into their design. SO does the AK *need* one or actually benefit is conjecture. Back in the day when they were first being developed, I was told that Finland? or somewhere was actually contracting to use them on their rifles. No idea if that was true or not, but I'd like to find what they discovered if they did so.

My buffer experience on a factory-built gun was that it changed point of impact while bench shooting by several inches. As with biggun, its a mystery since the bullets leave the barrel before recoil forces develop, so I can't wrap my head around it. I'm sure there's a very simple and logical explanation.

There's a bunch of FUD about them destroying your rifle and all this but I have yet to see proof... "show me the money" Makes for good debates, however! :)

Or ones that came from the factory that way, like the ORF Galil receivers.
Who makes these AK buffers? I have never seen one.

Anyone have a link?

Nobody ever said anything about 'destroying AKs'.

They have caused H&K G3 type receivers to crack where the butt stock is pinned to the receiver.

This is because the gullible owners have no clue that their H&K already has a buffer in it, and stick a one inch polymer puck in front of the factory buffer (because it'll make their rifles run better [according to the advertising, anyway])


My point being: Do you honestly think these buffer manufacturers are smarter than the engineers who designed the weapon in the first place?
AKBuilder.com has these buffers made up. $10.95 ea.

I think I don't care either way, to be honest.

I have read with my own eyes that people have stated that since the AK buffer forces carrier-to-receiver contact by taking up the dead space, that the rivets will egg out the holes over time. I've read that. On the surface it sounds good until you see the slow-mo vids of factory AKs hitting the receiver anyway. So IMO the jury is out on that one until someone can document the evidence.

But like I said I don't care either way. They do change the behavior of the rifle but they are not magic pixie dust... I cover my factory leather steering wheel with an aftermarket leather steering wheel cover because I like the way the bigger wheel feels. Doesn't mean I get better gas mileage however! :D
they may help certain AKM's that are worn where the bolt carrier cut out is or on some century built akms that have the cut out for the bolt-carrier too far forward.

in a well made receiver though they pretty much do nothing.

in one that ain't cut in the right spot it will help keep the bolt carrier from hanging up.

if you have some hot loads they may be of some use.
I got one of these buffers on order from AKBUILDER on the way. I will tell you how it works.
found no difference in my romy with the buffer. some of this stuff is like golf equip,you won't lower your score but you will releive your wallet. buy more ammo.
I installed the recoil buffer into one of my AK builds. It is a lot like the one in a PPSH41. It keeps the carrier from slamming against the rear trunion while using HOT loaded ammo. And, before I installed this part I sometimes would get the carrier stuck if I pulled the charging handle back very hard and lifted up on it. This part fixes that as well. The system operates fine.
Jumping off the rails

I'll add to the discussion that a buffer is a good way to fix rails that were cut too much that cause the carrier to jump off the rails.
That sounds like a good reason to get one.

My carrier kept jumping off the rails when I was trying to reassemble it after cleaning. And the rifle was factory-built.

As with biggun, its a mystery since the bullets leave the barrel before recoil forces develop, so I can't wrap my head around it. I'm sure there's a very simple and logical explanation.
Shouldn't it help keep the rifle steady, however, on the next round fired in semi-auto? I mean, assuming recoil actually is reduced with the device, wouldn't it be easier to stay on target with continued semi-auto firing?
