Compatibility: For Matador, Tokyo Marui, TSD, Matrix, JAG and other compatible Airsoft shotguns.

• The Tapp M4 Modular Adapter converts your traditional airsoft gun to use HPA and accept 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
