after a dozen design revisions and prints I've got it to where it fits and feeds as good as a factory howa,
and I've even eliminated a problem I had with the bolt running into the back of the factory mags preventing feeding when the factory magazine was pushed in too far,

i'm not a dealer so in keeping with the law, I'm not selling or otherwise supplying these so if interested don't ask only made them for myself.

here's a few photos and a link to more for those that are interested in the build, with some photos of the factory howa mini mags thrown in for comparison.
printer was a Ender 3 pro V2, with PLA filament cost coming in at $2.57 for the mag base and follower, springs came from aliexpress, 1.3mm x 8mm x 51mm x 155mm costing a hefty $11.17, would really have me questioning how the factory mags cost about $90 to buy but hey that's capitalism we take the bad with the good,

That looks awesome, well done.
Do you have issues with the feed lips bulging out when fully loaded? I never got 10rd Howa Mini mags to work with anything but expensive PETG carbon filament because of that issue. I guess there is a lot less pressure in a 5rd magazine.
