Louis,
Your quest for a magazine for the Krico may be a challenge. The Krico was a loose copy of the ZKW 465 although the bolt cocking piece design was changed somewhat. The Germans actually stretched the action (and bolt) by .5 inch to fit the .222 whereas the Czechs simply shortened the rear bridge on the ZKW by the same amount and opened the mag well to make the Fox. In spite of rumors of their existence, I have never seen a ZKW 465 factory chambered for anything except the Hornet. If I remember correctly, all the Fox series and the later CZ 527 rifles all used a side mounted lever to release the magazine whereas the ZKW uses an inside the trigger guard button at the rear of the magazine. This means the mag catch arrangement is different on the Fox than on the Krico. You might be able to modify a Fox or CZ 527 magazine to be functional. I no longer have a Krico here to compare with a ZKW or CZ. There is a Krico magazine on Ebay now that looks to be correct; however it has a $299.00 US price tag plus the possible export issues for you.

Best of luck.
John
