PolarStar Hop Up Thing – AEG/HPA Hop Up Unit

Precision hop-up units built to sloppy off-spec cast parts standards, that’s not this. The PolarStar Hop Up Thing is CNC machined in-house from 6061 T6 aluminum to tight tolerances, giving you a hop-up chamber that fits and seals the way it’s supposed to every single time. TDC Slider System At the core of this unit is PolarStar’s Top Dead Center slider design, applying consistent vertical pressure on the bucking instead of the wobble-prone sliders found on cheaper units. The result is a more repeatable flight path and tighter groupings shot after shot. Built for AEG and HPA Compatible with standard V2 M4/M16 platforms, this hop-up is modular enough to be tuned for either an AEG or an HPA build. It’s a full aluminum unit with a numbered adjustment dial for fine, repeatable tuning across different BB weights. Everything You Need to Install Rather than leaving you to source parts separately, PolarStar includes a 0.305″ gearbox lip suited to most AEGs, a 3x4mm round nub, an O-ring retaining tool for the small axle O-rings, 5 shimming O-rings, and a molded barrel clip. Specs: Compatibility: Standard V2 M4/M16 (AEG and HPA) Material: 100% machined 6061 aluminum Adjustment: TDC slider system, 3x4mm nub compatible Manufacturing: Made in the USA, ISO 9001:2015 certified facility If you’re tired of hop-up units that shift under recoil or leak air at the worst moment, this is a straightforward upgrade built around fitment and consistency rather than marketing buzzwords.
