We M4 double hi-cap

For sale a double hi-cap magazine for we M4 (and all other we based platforms that use M4 style magazines)

hPa powered, working pressure 90-120psi depending on your gun. 
I recommend 100-120 psi and npas to adjust fps

BB capacity ~650bb:s. Filled from the hi-cap magazine. Flash magazine, so you pull a rope to wind the hi-cap.

You can choose Us or EU foster fitting

Shipping within EU is around 20-30€ depending on your location
