Product Description
PolarStar - JACK Direct Attach Conversion Set
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. Polarstar got tired of "good enough" alignment. So they made this.
The PolarStar Direct Attachment is a replacement for the original front cylinder on your JACK.
What gearbox does this fit?
Short answer: it doesn't exactly need one. The Direct Attachment replaces the front cylinder on your F2 or JACK and connects directly to The PolarStar Hop Up Thing, allowing the engine to mount directly to the hop-up itself. In a traditional gearbox, the upper shell positions and aligns the HPA system with the hop-up. Because the alignment is now built into the Direct Attachment front cylinders, that portion of the gearbox is no longer needed. The electronics, and trigger/selector system can still be housed in a modified shell, a printed lower, or a completely custom chassis.
How It Works
It's a two-piece system: the Direct Attach Front Cylinder and an internal Adapter.
When you thread their Hop Up directly into this assembly, the HPA engine, the hop-up, and the inner barrel become one single, rigid, monolithic unit.
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.
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.
More About PolarStar and Why We Carry Them:
PolarStar Precision Airsoft was formed in January 2009 to fill a need for high quality, precision manufactured airsoft components designed for performance and longevity. The 2011 release of the patented Fusion Engine HPA system marked a change in direction for PolarStar. The focus shifted from developing upgrade components within the constraints of existing systems to developing innovative HPA systems and accessories which replace the aging AEG technology.
