Yesterday a good friend brought a gun of his that failed day before yesterday. It is a .223 Krink Pistol made by Elite Firearms.Net from Hurst, Texas on a Armory USA Receiver.

The problem was the bolt was only bearing on one side. Thusly it battered itself and the trunion apart.

If anyone else has a gun made by them it would be a good idea to check and make sure both bolt lugs are bearing.

The friend that brought it to me is the German factory trained gunsmith for Walther and Anschutz in the US. The gun had showed no sign of the failure beforehand.

I do not know even if 'Elite Firearms' is even still in business. Main thing I wanted to do was give folks a heads up that may have one of their guns.

The owner of the gun is going to use the salvageable parts to make a SBR after the proper paperwork goes thru. The bolt and front trunion are totally FUBAR, but the barrel will go into a SAR-3 to make a good SBR.

I did find out the web site for Elite Firearms is no more, but it does list the owner as Dave Michener and it gives a Fort Worth address and phone number. My friend is going to try and contact him next week.

Anybody know if he really is doing Saiga Conversions and Galil builds as well as AK pistols that his old web site claimed?

What is the origin of the parts the rifle was built on?

Youd think good friend factory trained gunsmith would caught it with his eyeballs himself

It WAS a matching Krink Kit. I do not know the country of origin as the gun is not here but went home with the owner.

Think about it, how often do YOU check the back lugs of the rifle bolts you are using? He IS good, but sometimes you take it for granted that the builder did know what he is doing and actually cared to turn out a safe, quality product.

In this instance the builder needs to be exposed as to turning out shit work! There is a reason the builder is widely known as 'Diamond Dave'. I have just found that out and wish I had known it a week earlier as the problem could have been easily fixed by a GOOD gunsmith familiar with AKs.

Scary! do you have any pics of how it failed/ broken parts?

The owner has both parts of the broken trunion as they fell into what was left of the receiver. As to pics, I am sorry but I am a dinosaur that does not have the capability. Hell, I do not even know how to 'text'.

How many rounds were fired? Was he bump firing it? I'm not factory trained, but I check my high stress areas in every firearm I take out when I clean it. This is all just a "fish story" until there are pics and a good history.

If it was a matching kit the lug contact was/should have been set when the rifle was originally built in Russia. I don't see how non uniform lug contact would cause a catastrophic failure, I could see it causing deformity on the one contacting lug. I suppose it's possible, but head space would have been opening up for a while preceding.

Are you saying one lug was missing entirely? That would be highly irregular and indicative ( in my mind) of a defective part and not necessarily a builder issue.

4 rounds were fired that day that were slow semi rate.

The lugs were not off the bolt. They were BOTH sides of the trunion!

Actually 'head space' is accomplished when pressing in the barrel in the trunion. That was PURE Diamond Dave.

After examining the barrel closely we 'think' it was originally a 5.45 barrel that had the chamber reamed to .223.

We came to that conclusion as it really didn't want to feed .223 with the bullet guide it had.

Not to split hairs, but if it was a matching kit the barrel pin groove was present and once lined back up to the pin hole on the trunnion the HS would be back to where it was originally set. It would be firmly set once the cross pin was installed. I do not see how he could have jacked up the HS if it was a matched kit, HOWEVER if it was improperly set by the factory it would be off no matter what. The builder should have verified HS after re assembly. Even if he did, it could have been a bad trunnion. Pics would be nice.


Wait...what? Reamed to 223? This is making less sense as we go lol. Slug the bore and measure. Again..pics.

5.56 AKs are a lot more complicated than 5.45 and 7.62. There is no uniformity among types from different countries. Some are built of the AK/AKM and others off the AK74. barrels, trunions, bolts, carriers, bullet guides - all of the same caliber, are not interchangeable. It's been my nightmare.

Your article should be titled "AK VARIANT Failure" 'cuz errybody knows it is unpossible for an AK to fail.

Errybody knows this. Errybody.

Would this be more of an overpressure situation? i.e. firing 5.56 rounds down a 5.45 barrel?

Also, you are assuming the builder lined up the barrel pin. You can still press in a barrel pin and shave off a little on the pin groove of the barrel. Which is why you should check your headspace before placing your barrel pin . Just eyeballing through the barrel pin hole is not an accurate measure of returning the build to proper headspace.

Fair assumption, I figure, since resetting HS is an elementary part of a build. I have not had a build fail HS after eyeballing the pin channel, have you?

I have not, but every so often the barrel sort of loads and pops a thousand or so past and I have to press it back out a tad and start the aligning process again. But I check my headspace even if it looks perfect the first time. Builders are assuming their kit was a demilled "in-spec" rifle before it was chopped. There exists the possibility that, in that bulk purchase of rifles sent to the blow torch, that they padded those numbers with some out-of-spec rifles. There are a lot of builds floating around out there made with careless hands. I've purchased a few, knowing they needed rebuilt, for a good price.

Lol. Yes. This pistol sounds like it was some sort of 556 frankenbuild. Or, perhaps, others are right and the builder was just that terrible.

Warning to the OP, trying to mate whatever parts your friend has to a SAR-3 may be a lot trickier than what you might think. My advice is: if its bulgy, stick with bulgy, if its saiga, stick with saiga, if its sar3, stick with sar3, yugo goes without mentioning. Front trunnions, bcgs, bolt heads, barrel journals are all different.

It is going to a reputable builder to be put together. Friend and I would never try it by ourselves. Most guns yes, but this one is going to a AK specialist.
