Has anybody come up with a better DBM for the Howa Mini? I've got a lot of projects I'd love to use a mini-action on, but right now the CZ 527 and the Howa seem to be the only games in town. I've read about the replacement bottom metal for the Howa, with a better magazine release, so that solves that problem - but what about the magazine itself? I haven't had any luck so far finding alternatives online.
