KWA MK45/USP M4 Adapter

Compatibility: KWA USP/HK45

• 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, 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.
