GBBP Mp5/HPA mag conversion remix

thingiverse

EDIT: Updated to include Glock, Hicapa, and GTP/SMC9 versions! the SMC9 version is the smoothest and most recent. The feed tube actually works. Make sure your printer has good dimensional accuracy or it wont. That's a tight fit in there to make everything flow smoothly. The end that is just two walls points down. It fits larger mp5 AEG mags. The original only fit my KingArms PDW midcap, I removed the "back strap" on it so that it will fit CYMA stick mags, as well as most high caps. The back strap does not help retain the mag as much as you might think. give it a shot and try to pry them loose ;) The magazine baseplate feed hole was adjusted to be roughly 7mm to account for printer tolerances. Maintained the same chamfer. In the future if I get it in my head to do I'll add a detent there to prevent the bb's from spilling out on mag change. I included the magazine release for posterity so you don't have to source the download from two places or in case OP deletes his design.
