Old tired Maadi

[branflakes]

At the range today shooting a Maadi.  It would fail to eject.  Another time two rounds were trying to load.  I had put the bolt return spring(?) from my Mak onto his Maadi.  Shot it without the dust cover and it ran much better but eventually bolt jammed up and did not charge home.  Barely contacted the next round. Slowly doing action by hand it seems to catch halfway forward.  The upper hand guard has play in it.  The pin that holds it does not make contact.  Extractor spring was much softer compared to my Mak. 

Some pictures of the action and bolt group.  I want to clean out all the rotating parts and contact patches but I do not think that it will fix the issue.  Mags that we used were, us palm, kci (with Wolff springs) and Romanian surplus.  I need suggestions on how to chase this issue.  Cheers!

Other issue is the pin for the folder will slide out with out with some wiggling of the rifle.  Pin is just straight from what I could see.  Did not have a mic with me.

I would say that bolt group has seen better days

The channel in that carrier is extremely rough looking. I will take a look at a few of mine tomorrow if I get a chance but I don’t remember seeing burrs like that on any of them including older WASR rifles.

Is this a USA built kit build?

The FTE can be caused by a few different issues, and you named a couple. A bad ejector spring is one. A loose UHG and gas tube is another. Sounds like to me you are loosing gas pressure. I would check the gas port to make sure it is clear and clean. The other issue where 2 rounds tried to load is a mag issue where the feed lips are spread too wide. Good luck.

That bolt group looks quite worn. If it were mine I would replace the bolt group and update with wolf springs. BUT! I am no expert on troublesome or worn ak. Maybe the guys here can suggest a less expensive alternative first.

I am not sure of where it was made.  Should have taken more pictures.  The kid took it on a trade.  I do not like that it was painted black at one point.  The entire rifle.  Inside receiver, on bolt, outside of barrel, dust cover.

UHG, am I able to crimp the open end so it doesn't sit so low on the gas block?  Would replacing it be better?  The bolt return spring on the maadi has two wires hooked together under the spring and my mak has a rod inside another rod.  I like the rod version better.  Is there somewhere to look for used and new old stock or new ak parts?  (extractor spring)  Google is getting more and more like amazon.  You search 'ak bolt' or 'ak spring'  and they come up places to buy stickers. 

He is a town over. I am waiting for him to send me some pictures that I have requested.

Where can a bolt group be sourced?

Also, are there different sizes or specs of bolts from different countries?  Does Chinese differ from Yugo?  If I get American made parts, do they need to be specific for this rifle?

These guys typically have a lot of AK parts.

I would also check Numrich.

If my memory serves me correctly the Maddi AKM’s aren’t typically high on the desirability scale. I believe most came into the US as Avery worn parts kits at a time when home builds and poorly done commercial builds were very common.

Did you happen to notice any import marks?

[Lafayettegregory]

from looking at the prices of parts on GB you might be best served by buying a parts kit at about 229.00

the only MAADI that I know of that real rough machining like that in the bolt carrier channel and the carrier, are the MISR ones ie. MISR-10 AND MISR S/A,..

Some MAADI rifles came in as new rifles, with thumbhole stocks before the 94 ban.

Headspace will/may be an issue if you replace the bolt, barrel, or front trunion. AKs are not drop in parts on major headspace parts like an AR.

My advice here. Inspect the FT, receiver, barrel, and bolt for wear. If they all look serviceable or repairable, move on to other parts. I'd replace the springs and extractor spring first and see if that clears most of it up.

MAADIs came over and were built up without clearing up the issues they had when they were imported as kits. They're not beginner AK builds due to it.

It doesn't look bad. He also isn't showing us the wearing surface of the bolt, he's showing us the face. The rear of the lugs controls the lockup. The carrier looks a little dinged, but not bad at all, some light filing will clean it up. I'd be more concerned with how it got dinged up.

When clearance is measured in thousandths of an inch, a 100th is a mile off. Just my .02cents worth.

On what part? The carrier doesn't set headspace.
