AK Magazine Question
 

I have a Mac 90 AK and looking for a few more magazines for it.
It is chambered in 5.56 NATO (223 Rem.) Looking for a company who has them for sale.

You should try 5.45 mags. I use 5 round .223 mags w/ my AK74 5.45 without issues. The only difference is the follower on some. The 5 round mags I bought had the same follower as My Bulgarian 5.45x39 mags. We tried a 30 rounder in my buddies Wasr .223, it held 32 rounds and functioned fine until it had a failure to feed on the last round.

Thank you for the information. My cousin has a Saiga that shoots the 5.45X39 and I believe that is the same magazine you are referring to.

Saiga mag is a single stack, Bulgarian mags are double. Totally different mag.
You could also contact Tapco and see if there Galil mag will fit.
Here is a link to the 74 mag. If you can find .223 marked followers, you would be all set. They may work well as is.

You might be able to modify Bulgarian 5.56 "Cirlce 10" mags to work by filing down the back so they fit the MAK magwell. I did this for my Romanian SAR 3, and they work really well.

Thanks for the information. I have made a note of this information for future reference. I got in touch with Pro-mag today and they advised their AK A-5 223 Mags will work in the Mac 90. So I ordered three of them. I will let you guys know if they work. They advised if they did not I could send them back if in original condition. I guess it is worth a try. I have had the MAC 90 223/5.56 for some time. It was before they required them to have the thumb hole stock to be imported. Has the wood AK Pistol Grip, Hand-guard and Screw on Flash Hider. But only had the original mag I bought with it. Great little rifle and I love to shoot it.
