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

  • GATE Pulsar-S engine (compact HPA engine with integrated electronics and precise trigger control).
  • BEGADI Neptune PRO chamber (high-precision CNC hop-up chamber with lateral adjustment system optimized for HPA).

This kit guarantees perfect alignment between the Pulsar-S nozzle and the Neptune PRO chamber in the SCAR-L platform, eliminating common HPA misalignment issues and improving feeding consistency. Fully compatible with ICS lowers and adapted V2 gearboxes.

What the kit includes

  • Rear clip for mounting using the rear body pin or fixed stock.
  • Base with housing for M3 threaded inserts (optional brass inserts for increased durability).
  • Side clip for routing the Pulsar-S HPA line.
  • Front locking top cap optimized for the Neptune PRO chamber.
  • Rear plate with mounting point for an M5 screw (additional structural reinforcement).

Installation and adjustment

1. Printing and preparation

  • Print the parts with 65–80% infill.
  • Lightly sand internal areas and contact surfaces to ensure a smooth and precise fit.
  • Apply dry lubricant or wax on sliding surfaces to simplify maintenance.

2. Installation in the SCAR-L replica

  • Insert the base into the ICS lower receiver and install the M3 threaded inserts.
  • Mount the rear clip aligned with the SCAR-L rear body pin.
  • Install the Neptune PRO chamber with the inner barrel; the top cap locks the assembly while keeping everything perfectly centered.
  • Route the GATE Pulsar-S HPA line through the side clip, preventing friction with the SCAR chassis.

3. Final fixation

  • Secure the rear plate with an M5 screw and washer for maximum rigidity.
  • Verify that the Pulsar-S nozzle enters the Neptune PRO chamber perfectly centered, without lateral play.
  • Configure the Pulsar-S firing modes and perform dry feeding tests.

Required components (not included)

  • 4× M3 × 4.2 mm threaded inserts
  • 4× M3 × 8 SHCS screws
