Norinco NS522 build: NEW MAG RELEASE

Here's an update.

After soaking the bolt in penetrating oil for a day, the ejector finally loosened up. While that was soaking I went at stoning the trigger. Lots of gritty creep on takeup.
Found that the spring had a burr and the dished out parts of the bolt sear and trigger where the spring rides had lots of machine marks. Amazingly enough the trigger sear and actual bolt sear were nicely stoned, but not polished. All machine marks removed and areas polished at contact points and I will install an over travel and takeup set screw later. At least now the trigger is a smooth clean break @ 3lbs. Just waiting to hit Dollarama for some hair clip springs. I'm looking to get a 1lbs trigger weight or less.

Since the ejector was working again I decided to test the rifle for function. Very hard feeding from the mag and lead shaving after a few rounds caused me to stop and analyze that.
Found a burr below the one ejector on the bolt that was gouging the case rim. Filed and polished that along with the sharp edge of the ejector.
Will try that again tomorrow and see if that works better.

Then I went at free floating the barrel and screwing in some lamp nipple pillars. These nipples really make it easy for a rimfire. On a centerfire I make my own aluminum ones on the lathe. Damn that Chu wood is soft and fibrous. You really need pillars.
I'll test it like that and see if this gun can shoot before glass bedding and other tweaks. Here's hoping it's a tack driver.
BTW, I did find it has a match chamber. Loading bulk ammo guarantees you have to shoot it. The bullet jams into the rifling and won't come out loaded unless you use a rod through the muzzle.
 
EHG, I've found that feeding issues are quite common on the 522. One of mine came with an aluminum single shot adapter. Some people claim these came with their rifle; others insist that someone must have made the thing. No matter, it worked well and I used it almost exclusively. Someone on the forum here has made a s/s adapter out of some sort of plastic stuff. You may want to look in that direction. 522 mags are rare and expensive, though it looks like the release of that new version of the 332 might change all of that. Best of luck on your re-work of a fine little rifle!
 
Yep, I'm beginning to think this bolt and action was never designed for mag feeding with the original mags.
The chamber is tight to begin with and despite my effort to fix the feeding the twin extractors were not designed to take the rim from the bottom and slide up.
They work best straight on. I don't want to rework it anymore as I may end up causing ejection problems.
No problem, I'll make up an aluminum single shot with the Bridgeport.
 
Mine has always fed fine.


Well, as fine as a Norinco will with a Match chamber and rough tooling marks.

This action and bolt are not a Norinco design, so they have several key attributes borrowed from other designs. I found the feed ramp and the mag lips are needing the most attention in pretty much each example I have worked on. I could not even begin to try and single feed the action as the ejection port is just that (an ejection port) and not meant for single loading.

perhaps some pics of your feed ramp?


If it will help, send me a PM with your email/cell # and I can send you a short video of a few examples I have here feeding from the mag as they should.

What feed ramp?
There is a drop from the chamber mouth, but I see no ramp like a ramped .45 barrel.
Reminds me of the High Standard pistols where the mag is the feed ramp. Adjust the mag for feeding and avoid shaving.

Here's a pic. You can see where I polished a radius where I thought the lead was shaving, but I'm thinking I need to adjust the mag lips to get the rim up slightly.

Ok, well,

I think you will be destined to single load it then. I LOVE single shots! Especially .22s. Nothing is better than a summer day and a Winchester 67/68.

But,

If your NS522 will not feed reliably then it is surely broken and needs to be fixed. All of mine feed ( within a tooling mark reason) pretty well. I do love a single shot .22, but the NS is not a single shot and single loading it would drive me nuts! Especially if it is supposed to be a reapater.

To each his own applies for sure.
 
Hey all,

Just a reminder to everyone that I am always here for any and all with pics, help or troubleshooting. If anyone has any guidance to give then dont be shy! We are all here to gently rib the CZ, Annie and Savage crowd with a little eggroll action!!!!

Thanks again to all.

Yep. Its the mag lips for sure.

Your "feed ramp" looks great and you did a perfect job, so your mags and perhaps a wee bit on the bolt itself?
 
Check your extractor and ejector to make sure the rim isn't getting hung up when it is leaving the mag. I had to file a bit off of both of them to get mine to work properly.

Thanks Scott,
From that I stoned the ejector a tiny bit, then radius/polished the edge where the rim rides up and I also polished the underside of the bolt a little where the rim comes into contact.
The extractor was not a problem on mine.
Problem solved, smooth feeding, no more lead shaving with both mags and good ejection.

Now to installing the scope and testing ammo. :)

EHG, you had asked about a pic of the trigger work done to my 522 by J.C. Blauvelt. This is the only one I could find (deleted the rest). Sorry for the out-of-focus (lack of) quality, but if you squint hard enough, you can see the set screws. One in the front of the trigger housing for over-travel, and one on the end of the trigger itself, that bears against the bottom front edge of the trigger housing for sear engagement. 4-40 set screws.

Thanks minimouse. That confirms what I visualized.

17$ to ship one mag. Any other sources?

Well you could buy more then one mag...even the shipping costs out. Only other place I found is free shipping if you spend $100 or more so probably out of your league...lol. Plus they are sold out.
Or you could pay $100 for a NS522 mag off the EE or from Kangs in the US. That's what they go for.

I'm hording these new 332 mags, a steal at $20 and I don't see Chinese production being long term of these.
 
I suppose as soon as these sell out a slew of them will appear on the EE at triple the price. The site doesn't seem to allow you to order multiple magazines in one order at least it didn't when I tried. Anyways, Kool aid drank, magazine ordered.
