This thread seems to contradict the military guy in GD who claims AK's can't run more than 4-5k rounds before suffering from reliability issues/ parts breakage.

Very interesting look behind the curtain. The Vepr 12 info is particularly interesting to me. Let us know what you see if you guys end up running other Veprs. I'd be interested to see if they have the same issues as you've see with RPDs.
Are you running any RPKs? I'm definitely going to have to find time the next time I'm in Vegas to stop by (and hopefully get a tour of the back as well)! |

So this seems like the AK IS pretty indestructible. I mean, there are armies who aren't going to put this much lead through a gun. Not to mention I'm guessing these get full auto mag dumps? I'm guessing the average joe's AK will last several family generations even if it sees multiple SHTF scenarios.
However it seems like a beefed up reciever might really make these last. Do you have any Mac 90's? I thought they were suppose to have a beefed up reciever. Sorry if I missed you saying you do have these. |

I am in no way saying that all Serbian weapons are prone to this or the older Yugos are of the same quality.

Originally Posted By HendersonDefense: OK... here's something for all the guys with home-built guns. I built this gun probably 5-6 years ago, if not longer. Here's a little backstory about it. This gun was used for Foreign Weapons Training that we were subcontractors for at Ft Polk. We were flying out of town twice monthly and needed an additional thirty AK's for training. We were training military personnel with AK's, PKM', RPK's, RPD's and SVD's and for some reason couldn't get any other AK's at the time (can't remember why). This kit was not built the way almost everybody else builds them. The rivet holes were not dimpled, swell neck rivets weren't used and the cheap Hansen "bag of rivets for $3" were used with the exception of the rear trunion long rivets. I had to use the rivet trimmer for all the Hansen rivets and used a one of the rivet crushing jigs with the crushing arm that's used with a press. The rear rivet crusher was an even simpler design (can't remember the mfg?) that used a large large piece of square tube that you set the receiver in and on top of bucking plate. The top had a modified machine bolt the was also used with a press to crush the rivet. The two long rivets were factory Bulgarian rivets that I purchased from K-Var/Arsenal. This rifle was pulled off the line today today because the RSO couldn't keep the top cover from falling off. He brought it to the armorer who right away tagged the weapon. He initially thought it was a broken rear trunion (he only scanned over it while working on the M-134 minigun) but I happened to be in the back an noticed that it wasn't a broken trunion but the rivet heads were shearing and actually cracked a portion of the receiver. The weapon has had a bolt and a slant brake replaced. Other than those two issues, the weapon has been unremarkable. Headspace is still within spec and no issues with putting rounds in center of the target. The six trunion rivets are still seated flat against the receiver with no evidence of shearing visualized. The five trigger guard rivets are also unremarkable. BTW, the serial number is below 4,100. This is another weapon that has been part of the inventory even before opening the range. It would be fair to say this weapon had approximately 10,000 rounds through it prior to range duty and by judging from the maintenance log, we put an additional 60,000-70,000 rounds through it. We've had factory AK's lose rivets to include one WASR, several Century M70AB72T's and a Norinco MAK-90 but they all were lost at the front trunion. This is the first AK to have an issue with the rear trunion.

Ron!
First, thanks a million for the info! We owe you! So your milled AK's don't suffer the same failures as stamped and last longer between failures is that correct? |

i really would like the details on the yugo failed rifles. i know that the op stated they were imported by century, so that would make me believe they were imported in single stack form. the opening of the mag well would be a potential point of failure. also in a similar fashion the early yugos had single stack bolts, maybe the full auto failures were a result.
and if the rifles were ordered as semi auto then there might be a difference in the factory specs for the receivers. i know the control in this case are the wasr rifles that were opened up and made as semi auto sporters, but still out perform the others. does this just prove romania has better metallurgy or that zastava has weak steel and no/poor heat treat? i wish that yall would tune up an m92 and rent it out, for science and so i could sleep at night! |
