ARP9 Shotgun Shell Magazine

Custom-designed shell mag for practical DIY builds

Take your ARP9 to the next level with this custom-designed shell magazine. Securely holds 30BB shotgun shells and allows for fast, smooth reloads.

→Key Features

  • Built-in shell opener releases BBs efficiently
  • Release pin ejects shell automatically
  • Internal BB latch system minimizes loss — only 2 BBs per reload
  • Around 28 usable shots per shell
  • Support-free printing — just import and print

How It Works

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.
