Tim, the JTS M12AK uses rock and lock magazines like the Saiga, so yes the KS-12T/Komrad magazines should work. Have a great day!

while they should work the only way to know for sure is to try one if it works then buy more of them

Tim, I don't see why they wouldn't. Both the JTS M-12 and KS-12T are compatible with aftermarket Saiga and SGM Tactical magazines. So it should fit and function just fine. If interested here's a link to magazines specifically made for the JTS M-12 AK in stock and ready to ship. Hope this helps, link here............... budsgunshop.com/product_info.php/products_id/125800/jts+shotgun+xisico+usa+jakmag10+m12ak+12+gauge+10rd+black+detachable

Hi Tim, there are slight differences in the JTS and KS Series. I would stick with the JTS Magazines. Magazine and the note here : https://shoptexasgunexperience.com/firearm-parts/magazines/jts-group-m12ak-12-gauge-10rd-magazine-jakmag10/
