KSG Tapp M4 Modular Adapter


  • The Tapp M4 Modular Adapter converts your traditional gas 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. (Lowers can be found here)
  • Gas magazine included and pre-installed with single stack mod to allow faster BB flow.
  • Friction-less BB stop allows smoother feeding and prevents BB loss while reloading.
