So I was taking apart my BCM upper and spikes lower to clean it today and noticed my H buffer looks scratched. What would cause this. I have around 500 rounds though this rifle. Non of my other buffers look like this. Is this a problem?
It does not rub off and it looks scratched. I bought it from BCM as well.  Untitled by 1911xmd, on Flickr" />

It wouldn't bother me unless it gets MUCH worse. Could it be from the buffer retaining pin? Yes. No worries. What? That's bad then. The bcg should push the buffer back so it does not contact the retainer. If it was hitting the buffer retainer would it break it? |

Alot of reasons for this, and I do not have the one answer. Out of spec lower? Buffer retainer pin hole drilled at wrong location? Carrier OAL a little short? Unless it gets worse by alot or damages the retainer, I would not sweat it too much. Just my opinion tho.
Some with this problem are switching to the JP silent captured spring, I have no experience with those. |

It does not even look like it has a scratch on it. If the retainer was doing it wouldn't it be beat up as well as the buffer? |

The dead giveaway that it's the bolt carrier is the concentric wear pattern. It's from the inside and outside edges of the carrier. Smooth your carrier out a little by breaking the sharp edges on the inside and outside. Shoot it after that. Buy more ammo. Repeat the shooting. |

So my wear pattern tells its the back of the bcg? yes, the reality is that if you bang two pieces of metal together a thousand times, one of them is going to look worse than the other. FYI, this is not "strange wear".. strange wear on the buffer would be a group of dots in the middle (circling the H), or a line bisecting the buffer, etc... that would be strange wear.. |

Yes, if the retainer is clean then I would agree that it is the rear of the carrier and not the retainer as I first thought. The marking look as tho they extend lower than the retainer. Inspect the carrier for sharp edges as mentioned by others. |

| The buffer never touches the retainer pin until you open the action which lets it come forward and be stopped by the pin. With the action closed, the carrier pushes the buffer back off the pin, and that's as far forward as the carrier goes. You can also get long scratches across the face of the buffer from sharp lower corners on the carrier when you open and close the action. Its very easily remedied with a 'stone'. |

That level of wear is no big deal. If it was gouging the buffer, I'd recommend taking an emory board to the bur or burs you WILL find on the back of the carrier. It doesn't take much to smooth them away. Start looking at the carrier around the slot for the buffer retainer pin; that's the most likely place to find burs.
The tell-tale that it's not the buffer retainer pin is that the wear goes in farther than the pin reaches. Wear on a buffer is expected. Gouges aren't "wear," they're an indication of parts that have sharp edges where they shouldn't be, and that should be addressed. |

Your wear pattern is telling you that the gun has been shot. Keep shooting it, the gun is going to have some wear! It's a mechanical device that is hammering steel on aluminum at a high rate of speed. It's perfectly normal. |

The secret to never having any wear on your gun is to never use it.
So if you're comparing your buffer with pictures on this site, keep in mind that most people do not use their rifles a whole lot or they are replacing it after a while. Just because someone says, "I've been shooting this rifle since 1980 and look at how new it looks!" But what they don't tell you is that they replaced everything or they parkerized it. After a couple of uses you should start to see wear in places that rub together. Eventually it settles to a consistent wear pattern. However until it reaches that final stage of wear, it'll have some really ugly markings especially the four corners of the bcg that rubs on the upper. Eventually it'll be worn in enough to where it'll look good. Think of it like a baseball mitt. When you first get it what are you suppose to do with it? |

As I said, OP, your wear is normal and nothing to worry about. When the carrier pushes the buffer back, the buffer tends to rotate, which is how the carrier scuffs the buffer face. WORSE wear, like deep scratches and gouges, comes from "something being wrong," such as a bur on the back of the carrier. But yours is just scuffed - normal, expected, and not a problem at all. |
