I recently purchased a Sig 522 from a local shop to go along with my GSG5 as affordable carbines.

When I try to fold the stock up and lock it into the reciever its a no go.  While I will near never use it in this format...I would still expect it to work...  I have tried slamming it towards the reciever hard and it just will not attach...

Can the stock be replaced?  My factory one seems to have a considerable amount of play in it...?  

Last but not least my gas block is visibly canted...will this cause performance problems or just problems if I put a front sight on?

I'm just trying to make sure the gun will work to the best of my ability before wasting a long drive to the range and back....

I've never seen, or heard, of a 522 folder that actually locks folded. I gave up on mine. I just collapse the stock and it fits in my Condor bag.

Where is the play in the stock? Forward and back, or L-R? Not sure I know how to fix it, but I do know how to take off the collapsable part of buttstock for a visual check.

The gas block is fake (faux) and serves only to hold the handguards in place, front sight and sling attachment points. The gas block is held in place by a hex screw. The hex screw is supposed to fit in a horizontal, milled-out groove, on a retension block on the barrel. Just a guess, but they may have tightened up the gas block without the front of the hex screw being in the groove.

Disassemble by owner's manual instructions, take off your handguards and take a peek at the gas block/hex screw position. It's easy, but make sure you have enough slack to put the handguards back on after you adjust the hex nut. You may also want to know how to take off the gas block to remove the dovetail shim to put on a front sight. Easy stuff. Loosen up that screw and the whole gas block slides off the barrel. (I didn't do this for the front sight operation, but probably should have) I have had it off to troubleshoot front sight movement issues though.

(If the screw is in the slot and it's still crooked...You may have something else going on that I'm not qualified to talk about.)

On you way to the range, stop by the hardware store and buy some 1/8th in E-Clips - Read the "Guide Rod" posts.

And have fun!! Really. I love this rifle.  I've been through a sight and scope, spare magazine odessy too. (Still am) (Fun - Serious)

I had the same issue with the stock on mine when I first bought it. It will lock closed, but it takes a little time to get it broken in. Fold the stock and use both of your hands in a "clamshell" motion to squeeze the stock into its locked position. Grab it firmly and yank it off of the locking stud. Do this a few times and it will begin to fold and lock easily.

yup had the same problem with mine, it is really tight but can be done the first time.

The stud is on the right side of the handguard and fits the notch on the right side of the butt stock near the buttplate.


Send it back to get the gas block fixed, It should not be canted, pretty easy fix

I had to smack the hell out of it a few times, but I got mine to lock. Then pried it apart. It is easier now I have done it about 10 times.

I just got a 522 today, haven't fired it yet.  I couldn't get it to lock folded either, but I slowly applied pressure with both hands and got it to snap in place.

How do you know if the gas block is canted?  I need to check mine.

I had to remove my "gas block" entirely to swap the basic HGs for a set of fishgills. When I put it back on, I just eyeballed it as close as possible with the short rail on top of the rcvr. I use an RDS, so if the "gas block" were canted one way or the other, I wouldn't know it at this time.

I guess unless you have some true straight edge - say a steel yardstick with a clean edge or a laser-line, you can look for alignment, but as I said, if your only using glass of any kind - don't sweat it.
