TAPP HPA Pistol Modular Adapter

The Tapp M4 Modular Adapter converts your traditional gas airsoft gun to use HPA and accepts 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, MP5, 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.
Recommended 90-100 PSI.
