223 magazines

I have a couple of 20 rounders for my Ranch Rifle, but tend not to use them often because they're so bulky and stick out too far below the stock. I'm thinking the 10 rounders might be just about ideal. But as fussy as these rifles are about magazines, I'd appreciate any info you guys could pass...

Greetings, I am looking for 5 round magazines for my Target Model Mini 14. Could someone help me with a supplier? Alas, 5 round mags are the max we are legally allowed here in Canada for any semi-auto centre fire. We can have 20 or 30 round mags but they must be pinned to 5 rounds only. Thank...
