I have a bunch of "full size" 22LR mags, mostly Black Dog with a few of the grey/green CMMG.  They are too long for my scoped AR 22LR.  I've found Black Dog's 10- and 15-round mags, but they are out of stock *everywhere*.  

Anyone know anything about future availability?

Are there alternatives (short 22LR mags that are reliable) that are compatible with the Spike's style 22LR kits?

Thanks.

Ruger makes 15rnd mags. I got some from cabelas.

Try 44mag.com. They have the BD 15 rounders.
