M4 Shotgun Shell Adapter

After creating my Hi-Capa shell magazine, I decided to make one for my M4 as well. These magazines are designed for "low cap" days, allowing a maximum of 30 shots per magazine.

The M4 magazine uses the same mechanical parts as my Hi-Capa magazine, including the shell ejection and release mechanisms.
