Primary Airsoft M870 shotgun to M4 MAGAZINE ADAPTER

This is a custom designed laser sintered nylon adapter that allows you to use HPA (high pressure air) and M4 AEG magazines on your airsoft shot gun. To use it you will also need an M4 AEG magazine, “paintball” tank with low pressure regulator (0-140) psi, a hose with a Foster (polarstar) quick disconnect and of course bbs. The normal operating pressure for green gas is roughly 120 psi depending on the temperature. We recommend that you run you pistol near this pressure and do not exceed 140 psi. Keep in mind that higher pressures can cause excessive wear and damage to the internal components of your airsoft pistol.

I designed this adapter to even the playing field when playing airsoft with a shotgun as a primary against AEGs with hi-cap mags. Please watch the installation video on YouTube titled: Primary Airsoft adapter installation tutorial 

The metal quick disconnect fitting in the photos will come installed. The fitting is a US standard Foster Pneumatics 1/8 NPT quick disconnect. The fitting can be changed to any fitting that has 1/8 NPT threads. Be sure not to cross thread the fitting when installing a different one. The adapter does not come with a gun, magazine or any other accessories.
