An exclusive collaboration between Maxx and AirTac Customs

Tired of putting gold, red and blue hopups in your black builds? So are we, so we made the ATPRO Blackout Edition, the first Maxx hopup to be offered with complete black anodizing.

The ATPRO design is based on the latest generation of Maxx hopups (M4A/M4P), and works perfectly for both HPA and AEG builds! (+-1 fps deviation and consistent performance, we tested it!)

The Blackout edition comes in a sleek black anodized aluminum so you can shoot good and look better.
