Hey all. I have a bullpup I built and all I can use is 20 rounders. I had purchased several Hungarian when they were less than $12. A couple of months ago I bought some of the Korean units from Krebs. I hadn't even tried to load these until I read this post. Well wclardy you are correct, they initially only will take 19 rounds. I did some playing around last night. If you push down on the last round loaded with a pencil you will gain enough room to put the last round in making 20. This is a pain. I took the Korean apart and also one of my Hungarians. There is a difference in the length of the mag body. The Korean is .068 shorter and the follower seems to be about .050 longer plus the spring has 4 less coils than the Hungarian. The followers I have in my Hung mags are from Kvar. I got them to meet 922r. I took the US made follower and put it on the Korean spring and reassembled. It is now very easy to load 20 rounds into the Korean mag. Also I took the Korean follower and put it in the Hungarian and lo and behold, it only held 19 rounds also until the stack was pushed down with a pencil. So, the fix to this is to get some of the plastic followers from Kvar and put these in the Korean 20 round mags and they operate fine. I know this is a little windy but I didn't want to come off as some troll who doesn't know shit. Hope it helps.If you're interested, Classic Firearms is selling very reasonably-priced 19-round AK mags:

I've got 5 and my biggest (and only) complaint so far is that they market it as a 20-rounder, but that 20th round won't fit. They work well in my IO-made AK, which has a very snug magazine well that the TAPCO mags would stick in. Plus, it's nice to not monopod any more when firing (I also use 20-rounders with my ARs).
Why do you feel the need to post that?That or just load 19 rounds.
