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

  • PolarStar F2 engine.
  • MAXX Model chamber designed specifically for M4 AEG platforms.

This kit ensures solid and precise alignment between the F2 nozzle and the MAXX chamber, reducing feeding variations and improving shot-to-shot consistency in high-performance HPA configurations. It is compatible with both standard V2 gearboxes and ICS split platforms.

What the kit includes

  • Rear clip for mounting via rear pin or fixed stock.
  • Base with housing for M3 inserts (optional brass).
  • Side clip for routing the HPA line.
  • Front locking top cap compatible with the MAXX chamber geometry.
  • Rear plate with mounting point for an M5 screw providing additional rigidity.

Installation and adjustment

  1. Printing and preparation

    • Print the parts with 65–80% infill.
    • Lightly sand internal and contact areas for a clean fit.
    • You may apply dry lubricant or wax on sliding surfaces to facilitate maintenance.

  2. Installation in the replica

    • Insert the base into the lower and install the M3 inserts.
    • Place 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 assembly and keeps the barrel centered.
    • Route the F2 HPA line through the side clip to prevent bends or friction.

  3. Final fixation and testing

    • Secure the rear plate using an M5 screw with washer to maximize rigidity.
    • Configure the PolarStar F2 within the desired pressure range and verify that the nozzle feeds smoothly without lateral play or marks on the BBs.
    • Perform firing tests and adjust the MAXX hop-up using the dial/arm according to BB weight and bucking type.
