Anybody have any experience with wear like this? I'm thinking the bolt materiel is too soft. Thoughts? |

This is normal wear of the camming surfaces on an AK bolt. They will NEVER retain their original finish over the course of thousands of rounds, no matter what that finish is. As the surfaces wear in to each other, they develop a shiny bare metal appearance. This is actually good, as the surfaces gradually mate to each other, and operation of the action will become smoother over time.
The bolt carrier and trunnion will likely show similar metal wear patterns on the camming surfaces as well. You will also see this pattern on the locking faces of the bolt lugs. Some finish may also chafe off the sides of the lugs where they occasionally rub on the inner machined portions of the trunnin. Again, this is all normal over the course of 1000+ rounds. I think the video poster is not very familiar with AKs, or doesn't shoot them very much. |

Aren't these century parts nitrided? If so there shouldn't be any finish to rub off as it's not a coating.
EDIT - Now that I've watched it on a computer and not just my phone, that bolt is pretty gouged up. Some wearing in is normal, but those gouges and stuff sure aren't. |

All I know is from what I have read at the AKfiles site is if your going to actually shoot it much stay the hell away from the RAS47. But that the C39V2 is actually pretty darn nice and good to go. Speaking only about the C39v2, it is very much good to go. Mine has been excellent and has proven to be the most accurate AK I have ever owned. 1 1/8 inches at 100 yards shooting Hornady SST ammo. I have no idea who actually made it for Century, but it is better than the Polytech Legend I used to have. |

I think the video poster is not very familiar with AKs, or doesn't shoot them very much. I respectfully disagree. On a standard (CommBloc) AK platform finish wear and burnishing of contact surfaces is quite normal and as you noted, favorable to a degree. But what these Century rifles are showing is far from normal. Finish wear and burnishing is one thing but deformation of material (peening) is unacceptable. I have seen very high round count(10,000+) Arsenals, WASR's, FEG's, Norincos and Zastava rifles that did not exhibit a bit of metal deformation. Wear yes, and some of it pretty heavy but not peening and material deformation. When bolt lugs and camming surfaces on bolts are deforming with less than 1K or so there is a serious issue. |

I have several high round count Combloc bolts with similar wear, including what you are referring to as peening on the contact surfaces. Maybe not as pronounced as his but still there.
I doubt this is a problem but that's just my personal take. And I do not own an RAS47, so not trying to defend a purchase here. |

Just to elaborate on what you guys are seeing, I can feel sharp gouges in some places on the bolt and the carrier has that deformation on the front. BUT to give credit where its due the rifle shoots straight and I haven't had any malfunctions, even after I gave it the old heave-ho and popped off the rear sight adjuster. I'm still gonna keep it until I get past 1,000 rounds and then make the decision if I want to junk it or keep it.
I'm not happy with it at this point. |

What ^^^^^^^he said. The bolt and carrier aren't nitrided so as not to affect the heat treatment.

I would caution anyone to take what they read on Internet forums with a healthy grain of salt. The RAS47 may or may not in fact have issues, but it was condemned on the AK forums long before the first one was built (as was the C39v2). You don't have to look very far to find people waiting enthusiastically to heap scorn on any U.S.-made AK, regardless of whether such scorn is warranted. |
