The Purple Rain – Custom HPA Airsoft Build

The Purple Rain is a one-of-a-kind custom HPA airsoft pistol build designed for players who demand style, performance, and versatility on the field. Built upon the reliable Action Army AAP-01 Assassin, this setup combines precision-engineered internals with a bold CNC-machined upper, delivering both power and flair in every shot. Whether you’re running semi-auto for precision or full-auto for suppression, this build ensures you stay ahead of the competition.

The Maximus Kit Advantage

At the core of this build is the CTM Maximus HPA Frame Conversion Kit (Black)—a game-changer for AAP-01 users.

It integrates seamlessly with HPA lines and regulators, ensuring consistent air delivery, improved efficiency, and rock-solid durability.

With the Maximus kit, The Purple Rain becomes more than just a sidearm—it’s a fully-fledged primary weapon system, capable of dominating CQB arenas or holding its own in open field engagements.
