The Alignment Revolution is a Monolithic Assembly.
If you've ever spent hours shimming a gearbox shell just to have your nozzle tilt .5mm and ruin your grouping, you know the pain. We got tired of "good enough" alignment. So we made this.
The PolarStar Direct Attachment is a replacement for the original front cylinder on your F2 or JACK. (We're looking at you, Kythera users — it's in progress!)
What gearbox does this fit?
Short answer: it doesn't need one. The Direct Attachment replaces the front cylinder on your F2 or Jack and connects directly to The PolarStar Hop Up Thing — no gearbox shell required. Because the engine mounts directly to the hop-up rather than sitting inside a gearbox, you're not locked into any specific shell. Drop it into a standard V2 build, a 3D printed lower, or a completely custom chassis. The gearbox is optional.
How It Works
It's a two-piece system: the Direct Attach Front Cylinder and an internal Adapter.
When you thread our Hop Up directly into this assembly, the HPA engine, the hop-up, and the inner barrel become one single, rigid, monolithic unit.
Why does that matter?
Zero Nozzle Deflection — By locking everything together, there's no room for the nozzle to wiggle or lean when it's loading a BB.
Consistency = Groups — If the BB loads exactly the same way every time, the hop-up effect stays consistent. Consistent hop means tighter groupings. It's not magic, it's just better support.
Perfect Alignment — It's physically impossible for the nozzle to be misaligned with the bore. If it's crooked, you probably cross-threaded it. Don't do that.
The Best Part? We're leaving the rest to you.
We're using these in our own custom builds, wild 3D-printed projects, and with Monk Customs Oracles to achieve that "impossible" perfect alignment. It works. It's solid.
Whether you're dropping this into a standard shell to finally fix a lemon or building a scratch-made sci-fi blaster from a 3D printer, this system is only limited by your imagination.
