The PolarStar AK Hop Up brings true TDC performance and micrometer-style adjustment to your AK build. Whether you're running an AK74, 100 series, RPK, or AK12, this unit is designed to eliminate the guesswork and imprecision that comes standard with most AK hop up systems.
Wider range. Finer control.
Unlike typical AK hop up units, the PolarStar AK Hop Up offers a significantly wider adjustment range without giving up precision. The micrometer-style thread keeps every adjustment fine and repeatable, no more overshooting your ideal hop setting. It's built to work with any hop method you prefer, standard round nub, flat nub, flat hop, or r-hop.
Built into the PolarStar ecosystem.
The removable, threaded gearbox lip and feed tube match PolarStar's V2 architecture, so it fits seamlessly if you're already running PolarStar components. The gearbox lip's standard .305" ID is compatible with most nozzles, including the included AEG nozzle. Looking to go further? The AK Hop Up is also compatible with PolarStar's Direct Attachment Front Cylinders for a fully rigid, monolithic setup.
