Product Description

Features

  • Monolithic Alignment System: Rigidly connects the HPA engine, hop-up unit, and inner barrel into a single assembly for precise nozzle alignment and improved consistency
  • Eliminates Gearbox Shimming: Removes the need for traditional front-end gearbox alignment, simplifying installation and reducing alignment issues
  • Improved Air Seal & Accuracy: Maintains consistent nozzle-to-hop-up alignment to help enhance air seal, shot-to-shot consistency, and overall accuracy
  • Compatible with the PolarStar Hop Up Thing: Threads directly into the PolarStar V2 Hop Up Thing, creating a secure, movement-free interface
  • Reduces Component Movement: Prevents the hop-up unit and engine from shifting independently, ensuring reliable feeding and nozzle alignment
  • Ideal for Custom Builds: Supports custom receivers, 3D-printed platforms, and specialized HPA projects by eliminating dependence on a standard gearbox shell
