Compatibility: For Tokyo Marui, TSD, Matrix, JAG and other compatible Airsoft shotguns
- The Tapp M4 Modular Adapter converts your traditional airsoft shell rounds to standard M4 AEG magazines (super-feed mags recommended).
- Modular design allows lower to be changed to different lowers. This makes the adapter interchangeable between M4, ARP, Shotgun Shell, etc.
- Friction-less BB stop allows smoother feeding and prevents BB loss while reloading.
