Loose sks mag?

[Iron sights]

Hi all. I have an sks with a 6 position folding stock from ATI. i just bought a tapco interfuse detachable mag pinned to 5 rounds. It feels a bit loose when i try to move it side to side, front and back is not to bad.

Also, it is very easy to put in but when taking it out it is catching a bit on the back of the magazine. There are marks where magazine has been scraped by metal in the rifle.

Is this normal?

And yes the bolt is open.

I had emailed tapco before i got my mags and because of the different tolerances they may have to be modified to fit your rifle. Side to side mine are fairly tight, but i had to trim a bit on the duckbill on the front to make it fit better into the mag catch.
I still have the email with pictures they sent me showing where/how to trim it, pm me your email and i can send it to you
