Yugo M-70 (AK-47 Variant). Only single stack magazine will chamber

[iceman3k]

I have my Yugo M-70 that will only fire from a 75rnd single stack/feed mag. If I use a regular double stack mag, it jams and fucks up the round. From what I was told a few years ago, there is a block in the receiver that needs to be machined away to allow for proper double stack feeding. Who would you recommend in the Denver Metro area for a smith?

Did you install the feed ramp?

You need a normal bolt IIRC, the single stack rifles use a cut bolt that just strips the round from the center.
I don’t recall a block that needs to be milled/removed but it has been a few years since I converted one

Wow, I had forgotten about the bolts that work for single stack mags only.
The HK SL-8 was like that too.
We used to sell a lot of Yugoslavian AK bolts.
