Modify/Upgrade 223 MDT polymer magazine into Federal Premium 224 Valkyrie.


SKU: N/A Category:


Have a 223 MDT polymer magazine and want it convert into the Federal 224 Valkyrie?

We take OEM MDT 223 mags and custom modify the internals to work with the new Federal Premium 224 Valkyrie ammunition.

This is a short term solution until steel AICS mags have tested and are ready for release.

We offer this service in discount for sending in multiple magazines.
