Zastava m70 inferior metal treatment process?

[Tacit Blue]

I found this thread randomly. A few people have made the claim that Zastava didn't use the correct method for heat treating. The claims that are being made is that cracks and deformations at the front trunion. Most of the info is coming from a person called " M-60 gunner" who claims they do testing and demill work.

I always thought my M70 OPAP was built like a tank. I'll have to inspect soon.

" I have a one month old NPAP DF and I have heard of these stories with the bolt and carrier. I checked mine, less than 200 rounds through it and found the start of deformation on the bolt carrier tail and the channel the bolt rides in. If you check out AK Operators Union facebook page they are talking about these issues there. I have also heard stories of the hammer and trigger pin holes getting egg shaped."

i don't understand how people continue buying century JUNK even after all the junk they put out since the early 90s. these guys have 9 lives and just keep selling their junk to gun owners. problems with the Tantal, WASRs, FAL/L1A1 hybrids, G3 clones, MAS 49/56, their in house AKs, and now the PAP.

buy once, cry once.

home built AKs are better

Even if this is true for a batch or two of rifles, Century is not going to do anything about it other than tell you to go kick rocks. You also have to remember this is commercial gun, the parts are not checked at each stage on each rifle.

Zastava makes good stuff most of the time. Century is just their importer, but as it has been noted 100s of times they don't care about their customers

Zastava guns aren't made by CAI, they're an independent company if Serbia, and CAI imports their stuff. I haven't had any issues with my NPAP thus far, over a year old

Here's the AK operator union post. Looks like it is true on some rifles!!! Looks like it might be due to the Tapco G2 FCG.

Tapco g2 hammers will do all sorts of damage to guns if they incorrectly profiled for the type / model of gun. Saiga 223 and Romania SAR3 guns get their bolts messed up from use of these hammers.

Is the bolt carrier a 922R part made by Century? If it is than that explains alot......I know the muzzle break and Tapco G2 is obviously. I think you're right about the G2 trigger group. Who knows?

Here's a interesting email from Zastava.

Hello Mr. McNair,

First of all, thank You for confidence in our brand of weapons.

Regarding the materials for bolt and bolt carrier we use same materials as for military rifles and heat treatment is the same. Type of steel is not recognizable in the US or Euro standards because it is russian originated steel for military purposes. Also, these two parts are made from forged materials which guarantee high strength of parts for dynamic stress.

I hope that I gave You enough data for Your porpose. If You need some more data we will be happy to help You.

No it is not, that is a factory part. Here is a photo of tapco vs stock vepr hammer. You can see the difference in various angles

I don't know guys, general consensus seems to blame the tapco g2 as the culprit.

Other AK users at the akfiles have same problem. One guy even mentions his arsenal equipped with the g2 has the same issue.

Now the question arises any builders experience the same issue using the g2 in their builds?

OK...just spent a couple hours going through all of my "substandard garage built AKMs", all have G2s, all are demilled parts kit rifles, not one has any noticable mushrooming of the carrier or bolt "I did not mic the parts...just used my eyes and hands". These include multiple M70s UF and FS and a couple M72s. Several of my Yugos have 5k plus rounds down the pipe as they get out more than the others. All have spot treated receivers with no noticable signs "with the naked eye" of impending failure there either. I am by no means saying that this is not an issue on some rifles but for my pile of rifles...not so much.

You start to see a problem. Reinforce or make a new piece.

i don't understand how people continue buying century JUNK

Because it's cheap and in stock at their local gun store.

All my AKs are orginal barrel kits built on Nodaks. I do have a Zastava M72 RPK but that was built from a demil kit with original barrel
