    Wyatt's Mag Box

    Published by Alex on May 14th 2021

    VERY impressed. Drop in fit on B&C stock with Defiance action. Previously when I had installed a factory mag box, it took a lot of tweaking to get it to work. YMMV but for me this took NO tweaking and fed perfectly. Works great with factory follower and spring.
