I'm relatively new to the AK platform so I don't have anything to compare this with. There seems to be excessive wear to the carrier tail. I have 200 rounds fired in this build I just received. While there were no malfunctions, the rifle did seem to shoot a bit harshly (for lack of a better word). I won't mention who the popular vendor is...for now...Pics:
The rear trunnion doesn't appear to be taking abuse. Overgassed? Will this stop? Get worse? Cause problems? Solutions? Advice and opinions are appreciated, thank you.. |

I've seen worse, lot worse. But its normal. Its from the tail hitting the hammer as the carrier goes back. It may have already been there depending on how much the original rifle was used prior to being demilled. This. I would have given a better response but I'm pretty doped up on oxycodine right now. Damn ankle. |

Now....I'm no Dr. but I've seen them on......TV So....I know what I'm talking about

I was shocked when I noticed the same wear/peening in both of my FEGs. Apparently it is normal, as they said. The only good thing you can say for it is, the larger the area of the flattened tail, the more force is distributed/negated. That means it should get to a certain size and stop growing, or grow very slowly. If you work the carrier with a de-cocked hammer you will see that there is ample material on that tail-piece that could be lost before the bolt tail hits the hammer - probably more rounds than the life expectancy of the barrel.
In the engineering sense, you could guess that the carrier tail was not hardened because they did not want it to wear material off or deform the hammer - just another compromise in the design of a firearm or anything else. |

If you're concerned about it, get a BufferTech recoil buffer, it'll give your bolt carrier some standoff from the rear trunnion and it'll cushion the recoil a bit. It's not the rear trunnion that's causing that damage. Also, buffers don't cushion recoil at all. If there was ever an item that I slap myself for ever buying in the past was an AK recoil buffer. |
| In all my time on AK forums i've never know that to be normal wear.Ive seen and bought a few used surplus carriers and none have looked like that. Think of this situation, if there was an out of battery condition that "tail "would keep the hammer from hitting the firing pin, less tail more chance of hitting the firing pin. |

That area doesn't come into contact with anything but the hammer, and then only during the recoil cycle, to cock the hammer. I can't imagine what would cause that amount of peening. But I've never personally seen anything like that. |
