Does anyone make a good 5 round magazine for the AK. I bought a couple at a local gun show when i was in the US and they are useless without finding a way to possible modify them. These would be for the PSAK47 gen3 in 7.62 x 39. Also does anyone have a 10 or 20 round pmag plug to make the pmags 5 round capible. My country enacted 5 round hunting capacity for any center fire rifle and looking for options for wild boars.

Get some 5 round Chinese steel mags, those are best.
Unfortunately, they used to be dirt cheap just a few years ago but have gone up pretty quickly.

Most of those were 10's you can add a wood block and block them down to 5

I have a 5 round Arsenal that works fine, it came with my SAM7R.  They are pricey for a 5 round polymer mag, but if you need it for hunting the $23 mag is going to kill you.

I know they aren't surplus, but Tapco makes 5 round polymer mags. They feed great and are pretty affordable.
