Wbp jack is quite mag picky

Hey everyone, I recently acquired an absolutely beautiful Polish Wbp Jack. Everything is perfect on her from what I can tell. Only thing is this, I’ve noticed it’s quite picky with magazines. I’ve tried polish steel and Bulgarian steel mags so far and I can’t even get them into the mag well unless I literally use all of my force. Is this common for the jacks? Or did I just get one with an improperly cut mag well. The us palm it came with goes in and locks like butter. Anybody else have this experience?

I just talked to you over on the AK forum. Beautiful AK! I love mine.
What grip did you put on yours? Mine is a Polish grip.

Thanks man! You have the exact same one as mine too haha. Mines the Polish Bakelite grip they’re selling on AOA. Do you mind posting a picture of your mag well so I can compare it to mine when I get home?

I've seen that with Romanians, I just took a file and relieved the sides of the mag well carefully, stopping to check progress every few file strokes. It didn't require much metal removal and it solved the problem entirely. Touched it up with cold blue when I was finished.

What? The only AKM that I'm aware of to have come into the US with a neutered/non-original magwell was the original WASR 10 (with the "10" representing its 10 round single stack magazine), which was a "post ban" version cobbled together for legal importability into the US. This lead to US manufacturers producing AKM's in the US to avoid such importation restrictions. Then at a later date, the monkeys over at Century did a poor job of enlarging the magwells of their WASR 10 rifles in stock to accept standard AKM magazines, resulting in many of these rifles having very loose fitting magazines - because the Romanian receivers *did not have dimples to support the sides of the magazine when installed.

This lack of dimples can be seen in the Wikipedia WASR 10 image below:

Is this your first AK? Are you pushing the mag straight in?
I looks from the pictures that the front lip catch is not in the magwell.

The AK mag does not insert straight in like a pistol or AR. You can't push it straight in. It swings into position. First seat the front lip inside the magwell, then swing the rear into the mag catch.
The curved mag almost points forward when you start the action.

Best to watch some vids on AK reloads.

Try other mags. There was a time I had to write the AK name, or use a color dot matching code, on each mag so that I could tell which mag fit what AK--- until the Korean mags (as I mentioned earlier).
It became very confusing, as I had over 30 AK mags and 7 AK's. The source of the mag was not a predictor of fit. For example, a few com-bloc European mags did not fit my Saiga or Vepr AK without a struggle, magpul was too tight for others, etc...

I like the Korean steel mags, and they fit all the AK's I have-- easily attach, cost less then most, and drop free.
I like the drop free feature.
