I had that same issue with the one I bought for testing. I fixed the problem easily. When you take the mag apart you will notice the follower is too narrow in the mag. The lugs on the follower that are supposed to stop it as it rides up in the grooves on the mag do not catch at the top. The follower has 'shrunken' after being molded.
1) Take a wine cork and stab it with a fork. (Fix works better while drinking the wine!)
2) Insert cork/fork into follower causing the follower to bulge out.
3) Get a coffee cup big enough for the follower/cork/fork to fit into, and fill it with boiling hot water.
4) Using the fork, dunk the follower/cork into the boiling water for ONLY 10-15 seconds. IMMEDIATELY rise with cold water.
5) Remove cork from follower and test fit follower in mag. Repeat as necessary.
6) OPTIONAL: Finish bottle of wine to celebrate fixing your mag!
6A) OPTIONAL: Try saying 'follower/cork/fork' quickly and repeatedly after drinking bottle of wine. Hysterical!
Jeff, how is this fix holding up? Any problems with the follower returning to it's shrunken state, after putting some rounds through it?
I've got a ProMag and it seems I have the problem. See my pics in this post: http://forum.saiga-12.com/index.php?s=&...st&p=322154 .
Also, it seems I'm going to need to fiddle with it to even insert into the gun more easily. It's a pain, as is.
My mod is still fine. I don't expect it to change. The follower probably 'shrunk' originally due to too rapid of cooling after being removed from the mold. Once heated and reshaped it shound retain its new shape.
Almost EVERY mag will require some degree of fitting to work in a Saiga. It's not so much to do with the mag but with the manufacturing variances in the Saiga itself.
