AW-93 Extraction question

[Walter]

I'm having a bit of a problem with my aw93. when brass is being extracted, the extracting brass scrapes against the next bullet, causing either slight scratching or heavy gouging of the lead on the next round. My initial thought was that the magazines were both becoming worn enough to bring the bullets in the magazine into contact with the extracted brass, or that the ejector was a bit too high. upon careful examination it looks like the extracted brass should be riding on the top of the tabs in the front of the magazines. If they were being guided by the tabs, they would be held high enough above the bullet so as not to scratch them. If I slightly bend in the tabs, the brass hits the magazine and the extractor slips off the lip of the brass.
I'm wondering if there is a different way to adjust the front tabs, or, if maybe because the brass has been hitting the magazine for so long that it has worn the back of the magazines enough that they are riding a bit high.
It is causing malfunction in about every 200 rounds of wolf, and about every 30 rounds of aguilla subsonic.
If anyone is shooting the aw93, could you please check how the bullets are being extracted by your gun for me?
Thanks for the help,
Walter
