PSA re: bolt failures in recent import M-14 pattern rifles

Glad to see CGN is proving its value as a technical resource. The MIM bolt issue was never quite resolved in Canada, so let's hope it isn't reappearing in Poland.

There is a lot of technical knowledge on tuning M305 rifles here. Ask your questions and people will share.

Not sure about Poland but I have some info from Czechia - they had a bunch of Norinco M14 imported, MIM bolts... but only about 10% ever came back for warranty work. Either people are not shooting their rifles enough or they are not that fragile after all.

Just keep in mind that a bolt failure is a major pain in @$$ in European countries, where often individual pressure bearing parts, such as bolts and barrels, are regulated as firearms, and getting a new bolt is the same as buying a new gun. Particularly when you're only allowed to own a certain number of guns at a given time. That new bolt will count as a firearm on your list.

At the range I worked at, we had a lot of dead guns because it was such an administrative PIA to get things like new bolts... (we had like 3 or 4 dead Yugo MG42s, and you couldn't mix and match parts to get one good one...)

Anyhow, it's shocking that the Canadian importer was never held accountable for importing a defective product... They changed the manufacturing process to cut costs, and that process was not suited to, and gun blew up.

What's the "blow-up rate" on just about any other new production firearm?

Just remember that bolts are considered istotne części under the UoBiA (art. 5), so you would probably have to arrange for someone to import it. I guess a gunsmith could arrange it and then number the new bolt to match your gun, so you don't have to waste a promesa, or a line in your red book.

For everything else, see M14.ca and Brownells Polska.

Oh damn you're right. I forgot about those idiotic rules in our country.
M14.ca i will look into but Brownells pl is soooo expensive and out of stock

Below promised photos. Hope quality is better as i tried my best. My nikon did not want to focus from closer distances so i had to hold it further and zoom (right click on the photos and then copy image url so you'll get better resolution)

I would say your bolt looks nothing like the MIM bolts!

For starters, your bolt is covered in machining marks, and I guess the whole point of MIM was to make a part that required little to no machining.

So maybe this MIM process has been phased out.

The House of Guns post I found said they switched to "precision metal casting" for the bolts.

I guess it would have been nice if House of Guns pulled one out of the box and ran a few thousand rounds through it to show us that these things are safe.
 
From these recent pictures, I don't see the MIM circle I thought I saw in the previous pics you posted.
 
I'm curious to hear what the M305 Historians on this forum have to say about this:

On Friday, we will tell you a little bit about how it is with weapons made in China, namely why everything from China is incorrectly pronounced "Norinco" and why the same models can completely differ in the quality of workmanship?

so from the beginning . It is located in China. 11 firearm factories where you can order the production of such weapons, that is, the circle of companies that can order and export these weapons outside China is very narrow and covers only a few positions. Until recently, the main company exporting weapons was Norinco, a Chinese arms group. Hence, it was claimed that every weapon made in China is made by Norinco. No one understood that the specific factory that produced this weapon is of great importance to the quality of weapons, not the company that exported this weapon. Some time ago, our Polish House of Guns joined the group of several companies that have the right to export these weapons directly from the factories. They can order the guns directly from the factory. Each of the factories specializes in producing different types of weapons. One makes the best guns, another makes the best rifles, and another makes something else.

From here, if we order, for example, M1911s from a factory that specializes in rifles, their quality will not be the same as in the case of a factory that specializes in pistols. And vice versa, if we order M14s from a factory that makes the best guns, the quality rifles will be worse by force. So the most important thing is choosing the right factory for the right order and that's what the guys from Haus of Gans do. The M14s that they imported (known from the recent "one less" action) were ordered directly from a particular factory that specializes in the production of rifles and they really made them very well in quality. They have nothing to do with the flair art made back in the day for Canada by another factory. They also cannot be compared in any way with M14s manufactured by other factories in China that appeared on the European market. The specific ones we have are M305, there were also M21, M305B etc. Etc. �� It's the whole story, so to evaluate a particular production you have to take it in your hand, which we strongly encourage you to do ��

Looking at the guns that have been imported recently, a lot of components look basically identical to my gun. Would each factory just create all new tooling for... M14 stocks... for example, just because they got the order?

Is tooling getting passed around between factories on an as needed basis?

It sounds like a weird story to me...

Broad strokes…. That is an accurate statement.

I believe there were at least 4 separate factories that made M14 pattern rifles for the Canadian market. They were all branded differently.
 
Pretty sure it’s still prohib
If you get caught with one I don’t think you will be charged though
I think they will still confiscate your gun though so not worth losing it as you can’t replace it
Hopefully there will be more clarification on this as time goes on
 
So, not sure if this thread is still alive or not , but I recommend this rifle to a friend a few years ago and after visiting over Christmas he pulled the rifle out to show me that sometime last summer he decided to pull it out and run some 308 hunting ammo through it , bolt survived 3-4 rounds and completely detonated on the 5th looking exactly like the one at beginning of post. Now, what do we do about replacing bolt with propped USGI bolt?
