This HPA adapter represents the culmination of months of work to produce, from scratch, a shortened magazine for the GBB MAC11. This leads to an ultra lightweight magazine setup, that is both more enjoyable and economical than buying the gas mags.

There are a number of factors involved when designing a HPA adapter for this gun. We’ve taken the time to address these, ensuring flawless feeding, lifelong air-seal, and an excellent aesthetic.

PLUG AND PLAY - We've injection moulded our own gas router for this adapter, and combined it with our high flow valve and printed feed lips. This means no more donor mags!

MODULAR ADAPTER TOP

This is the 'top' part of the modular HPA adapter, and is available for purchase so you can use your existing modular bases, saving you money!

M4 

Compatible with most M4 magazines, works best with PTS EPM1. A CNC Magazine release and feed tube set this adapter apart from others on the market!

You can also choose from a variety of coloured magazine catches here.

Your adapter will come with a number of shims that can be used to ensure snug fitment of your M4 magazine.

MP5

Compatible with all CYMA MP5 Mid Cap Magazines. A CNC Magazine release and feed tube set this adapter apart from others on the market!

SHOTGUN SHELL 

Compatible with CYMA Shotgun Shells and some other brands. A BB release inside the adapter prevents any BBs from being dropped when releasing an empty shell.

DRUM BASE

Allows your HPA adapter to be used with a Tokyo Marui MP5 or VZ61 drum (or a Well/Jing Gong one if you can find them). The drum itself can be purchased separately here

MODULAR MAG-WELLS ALSO SOLD SEPERATELY!

Modular Mag-wells can be purchased individually here. I recommend mixing one high capacity mag-well, e.g. M4 or MP5 with a limited capacity mag-well such as the shotgun shell base, for those sites who don't like HPA adapters, or for when you want a more 'realistic' setup, while still running HPA.

DO NOT EXCEED 150PSI WITH ANY AIRSOFT HPA ADAPTER.
ALWAYS USE AIR REGULATED BY A SECONDARY REGULATOR (EG AT200, WOLVERINE STORM, POLARSTAR MRS).
CHECK YOUR PSI BEFORE CONNECTING AIR TO A HPA ADAPTER.
NEVER CONNECT OUR EQUIPMENT TO PAINTBALL AIR TANKS OR CO2 TANKS.
NEVER CONNECT OUR EQUIPMENT TO A TIPPMAN STYLE HPA LINE
