haugpatr 972 Posted June 20, 2013 Report Share Posted June 20, 2013 I sold a factory rock n lock 8 rd mag to somebody and they are saying it won't lock in to their gun. Do these ever require fitting to the gun? Quote Link to post Share on other sites
BlackSnake99 11 Posted June 20, 2013 Report Share Posted June 20, 2013 With Russian quality control I would say that anything is possible. Quote Link to post Share on other sites
haugpatr 972 Posted June 20, 2013 Author Report Share Posted June 20, 2013 I think that I have heard others say they had to fit them, but I just want to make sure. I can't see how a mag could be out of spec, but a mag catch out of spec would make sense. Quote Link to post Share on other sites
cguiro 29 Posted June 20, 2013 Report Share Posted June 20, 2013 The mag may not be out of spec... the gun maybe out of spec then. Magwell size differs trust me non of my factory mags fit in my buddies s12 Quote Link to post Share on other sites
haugpatr 972 Posted June 20, 2013 Author Report Share Posted June 20, 2013 I am thinking I should tell this guy to file a little bit on the rear catch of the mag? Quote Link to post Share on other sites
cguiro 29 Posted June 20, 2013 Report Share Posted June 20, 2013 Yea. Small amounts at a time. Test fit frequently. I used a little bit of hoppes oil when i fit my mags. Made filing go cleaner and easier. Left a nice finished look to Quote Link to post Share on other sites
ChileRelleno 7,067 Posted June 21, 2013 Report Share Posted June 21, 2013 IIRC, every mag sold with a new commercial Saiga, is factory fitted to that gun. There is enough variance to mags and magwells, that fitting a mag shouldn't be any surprise nor cause for concern. Heck, if anything I would be more comfortable knowing it fits my gun well.

ctd 20 Posted June 24, 2013 Report Share Posted June 24, 2013 All my factory mags came with instructions on how to fit them to your gun, printed in Russian Quote Link to post Share on other sites
scoutjoe 273 Posted June 25, 2013 Report Share Posted June 25, 2013 Used to be more common with earlier guns. Quote Link to post Share on other sites
gunfun 3,930 Posted June 25, 2013 Report Share Posted June 25, 2013 (edited) Yeah. If you payed attention while unpacking, I bet there were pencil marks of your serials on your factory 5. That was from when someone did a quick and dirty fitting. Edited June 26, 2013 by GunFun 1 Quote Link to post Share on other sites
gregomega 929 Posted June 25, 2013 Report Share Posted June 25, 2013 I have had to fit a few of mine Quote Link to post Share on other sites
Terminator03 18 Posted June 30, 2013 Report Share Posted June 30, 2013 I haven't had to fit any mags to the s-12 yet, but my m10-762 required several of the surplus 30 rounders that I bought to be file fit to it. As said there seems to be a lot of variance in the fit on these guns and I attribute that to variances in the stamped parts used. On an AR for example, you rarely have this issue since the magwell is broached to a specified tolerance, but AK style mag attachment relies on the stamped catch, and the front lip of the receiver cutout to mainly control the fit of the mags. When you add another stamped part (on a regular AK) into the mix that is just more tolerance stackup to deal with, or in the case of the s-12, you can still have this issue with molded mags built to a max tolerance when used with a gun made with a slightly oversized catch. Personally, I take the time to identify any issues with the mags I use and just modify them as needed to flawlessly function. Quote Link to post Share on other sites
