wolverine inferno 2 reaper 2 maxx model alignment kit

Version 2.1 of the hop-up alignment system, designed specifically for M4 AEG HPA replicas using:

• Wolverine Inferno 2 or Reaper 2 engines (compact HPA engines with high airflow and adjustable pressure configuration).
• MAXX Model chamber (high-precision hop-up chamber with quick adjustment system, widely used in HPA builds).

This system ensures solid and precise alignment between the Wolverine nozzle and the MAXX Model chamber, eliminating double-feeding issues and improving consistency in high-performance configurations (40+ RPS). The geometry of the kit is optimized to take full advantage of the compact design of both Wolverine engines.

Installation and adjustment

1. Printing and preparation

   • Print the parts with 65–80% infill.
   • Lightly sand internal areas for a clean fit without friction.
   • Apply dry lubricant or wax on sliding surfaces if frequent maintenance is expected.

2. Installation in the replica

   • Insert the base into the lower and secure the M3 inserts.
   • Install the rear clip aligned with the rear pin or the stock mounting point.
   • Install the MAXX Model chamber with the inner barrel; the top cap locks the entire assembly in position.
   • Route the Wolverine HPA line through the side clip designed specifically for its diameter.

3. Final fixation

   • Use an M5 screw with washer on the rear plate for maximum rigidity.
   • Verify that the Inferno 2 / Reaper 2 nozzle enters perfectly centered into the MAXX Model chamber.
   • Perform dry feeding tests and adjust the hop-up according to your BB weight and preferences.
