Sig 522 feed problem

[northumbrian]

If any of you, want to try and DIY it, cut some paper into a 1/2" strip and roll it up, then cut a small section about 1.5mm around half of the roll, to create a step.
Then insert the paper into the chamber with the cut out step where your going to file or grind the feed ramp.

By placing the paper in the chamber you reduce the chance of you trashing the chamber if your a little too heavy handed with the tool.

Still with them, and have heard nothing yet...

My problem with this is that there are many Sig522's that do not have the feed ramp blended into the chamber - but feed fine. This fix strikes me to be more if a bodge to fix an underlying problem with magazine location - either a bad batch of magazines (as garlands claim), or some badly moulded lower receivers.

I completely agree with you, it is a bodge.

But, if you have to do it, it's best to do it right, sometimes you've just got to do it.

Bad batches, are to be expected from a mass produced product.
With the Sig522, it's either the mag, or the lower, by the look of things.

It would seem SIG have let their standards slip somewhat.

I contacted BlackDog to discuss the possibility of there being a bad batch of mags, as claimed by Garlands, this is their reply:

there has not been a bad batch of magazines. most of the time is it the sig lower receiver, cause there is a high [wide] tolerance in them. some people say their mag is too loose some say its to tight.

Dear Sir,

I’m having some serious problems getting my new Sig522 to feed any ammunition from your 25 round magazines. One is the original magazine that came with the rifle, the other is another Sig/Black dog branded mag. The mags seem to sit too low in the lower receiver, as such the rounds enter the chamber at such a steep angle that they deform and wont fully chamber – the bolt needs a forward assist once ever 3 or 4 rounds!

The UK importer of Sig Sauer rifles claims that there has been a bad batch of Black Dog magazines, can you confirm this? I’m only aware of the mag follower issue with your metal lipped mags.

Out of interest, if I push up on the base of the mag and operate the weapon, it feeds and cycles perfectly. I’ve recently been in contact with 3 other Sig 522 owners that are experiencing the same problem, rifles were manufactured in 2012.

Hope you guys can help, or at least clarify the facts,

All the best,

Chris

Latest update for anyone interested. Got the rifle back with a different magazine, they demo'd it to me with a full mag of Winchester subs. Seemed to function fine. Tried it with another mag of Winchester subs when I got home, sadly it wasn't long before I started to get stoppages. Tried 3 other different brands, they were worse than the Winchesters, with loads of stoppages, especially with the RWS.

Then, with the gun quite filthy by now I tried pushing the mag up and slightly forward in the receiver. It fed the RWS absolutely fine, full mag without fault. Went home and cleaned it, manually cycled the Winchester subs to see if the bullets were still being damaged, and they were totally mashed. If I re-try whilst pushing the mag up they cycle fine without hardly a scratch on the soft lead.

Will try a friends lower this week, hopefully. That's the only way I can prove my sloppy lower receiver theory.

Cheers.

Nice that Bruce replied.

Never had any issues with BDM magazines and they are a good buch to deal with.

[northumbrian]

It's good that your getting somewhere with it, all be it slowly.
I am inclined to agree with your dodgy lower theory.

Have you got any feeler gauges? if so you might want to do a comparison, with a mag in place, with your mates lower and yours.
If the mag well on yours is larger than his, then that should "prove" the case.

Had a chat with someone today who was involved in the initial import into the UK of the SIG522 rifles, he is very much aware of a problem with recent imports that have defective lower receivers, too much lateral play. I managed to convince a club member to let me try his older (2010 I think) lower, and guess what - no lateral play, feeds 100%. You can rock the mag back and forth on mine quite considerably, but on the older rifle there is very minimal movement. I was seriously pushed for time so didn't have a chance to take any measurements.

As such its gone back to the shop. I'm requesting a refund or credit note to put towards something that works as intended, the guy I need to speak to doesn't work a Wednesday but the chap behind the counter agreed that if its been back to Garlands and still isn't right then I have a good case.

Fingers crossed.

Zimmer, this is a known issue with a specific batch of 522s. Garlands (the importers) know all about it and you need to speak to your RFD who will organise a replacement for you via Garlands.

I tried 5 different mags and 5 different types of ammo before mine went back to be replaced. Then as (bad) luck would have it, they sent me another from the same batch and it had to go back too. They sent me a new rifle from a new batch and it's been perfect. Not a single problem.

Don't muck around any more, your rifle's faulty, just get them to replace it.

Judders, do you know what year your rifle is? I think there is a date sticker on the box. Would be interesting to find which dates/(partial) serial number ranges are affected. Also, was it the 'classic' or tactical?

Cheers.
