300 Blackout Speedloader + Compatible Case (60)

This profile has two models included: 1: 60 round 300 blackout ammo box, fully 3d printed and snap fit. The box uses nubs to keep closed. NOT COMPATIBLE WITH 556. The box seats rounds using the neck, which has different geometry on 556.2: Speedloader for AR mags (also compatible with 556) The case is designed so that the speedloader can easily slide in, to load in rounds 10 at a time.The speedloader is designed to print with just a brim, and no supports, hence the kind of weird geometry.
