ARP9 Shell Magazine [STL]

Take your ARP9 to the next level with this custom-designed shell magazine, made for players who enjoy practical DIY airsoft mods. This mag securely holds 30BB shotgun shells and allows for fast, smooth reloads.

Push a shell into the mag, and the built-in shell opener releases BBs efficiently. When the mag is empty, hit the release pin to eject the shell automatically. The internal BB latch system minimizes loss — only two BBs are dropped per reload, giving you around 28 usable shots per shell.

We have updated the design to include "support-free" printing. Just import the files and press print. All files have the correct orientation

It’s a solid upgrade for tinkerers who want to bring shotgun-style reloads to their ARP9 platform while keeping function reliable and reloads satisfying.

Thank you for choosing to buy this file on my own platforms. It means a lot and helps me continue creating new models.

If you buy the files on my own website! I get paid quite a lot more, with no additional cost to you. Fees on Cults3D are around 20%. If you become a member of www.coff.ee/quizcen, you can get many files for free and up to 70% discount on all paid STL files.
