Build Highlights


The M4XIMUS Kit – Full Auto Power in an M4 Package

At the heart of this build lies the CTM M4XIMUS HPA Frame Conversion, turning the AAP-01 into an HPA-driven powerhouse with M4-style ergonomics and modularity. This isn't just an adapter—it's a complete transformation.

  • M4-Style Magazine Compatibility – Feed your AAP with reliable AEG mags, like the included PTS EPM1-S 170rd Midcap.

  • Pink Frame Aesthetic – A bold contrast to the dark and chameleon tones, giving the build a one-of-a-kind look.

  • Enhanced Stability & Comfort – Solid M4 grip angle and stock-ready buffer tube interface deliver improved control, making this build perfect for aggressive CQB or high-speed play.

The M4XIMUS Kit not only upgrades your AAP’s performance—but elevates its tactical and aesthetic footprint to a new tier.

Blending performance parts with a vibrant electroplate chameleon finish and subtle purple accents, this custom build brings function and flash together. From the precision-machined CNC internals to the dynamic visual pop of rainbow and purple tones, it's engineered for players who demand the best—and want to look good doing it.


Ready to dominate the field? This custom AAP-01 HPA build is dialed in and built for battle—whether you're chasing milliseconds on the timer or style points in the staging area.
