Polarstar F2 Starter Kit with Reg and Line for AK/V3

This starter kit pairs the PolarStar F2 HPA engine for AK-pattern and other V3 gearbox rifles with a Strike Airsoft regulator and flexible air line, giving you everything you need to convert a V3 gearbox AEG to HPA. The F2's velocity is set by air pressure alone, and its fire control unit is fully programmable. To run it, just add an HPA tank, such as our Nuprol 48ci or CGE 13ci, and a small battery like our Oper8 Mini HPA LiPo, and the rifle is ready to tune.

Our PolarStar F2 Starter Kit saves you £33.95 compared with buying the F2 engine, regulator and line separately, keeping the cost of your HPA conversion as low as possible.

PolarStar F2 engine

The F2 uses two solenoids, one for the nozzle and one for the poppet valve, so each can be timed independently. This gives very consistent shot-to-shot velocity and a near-instant trigger response. PolarStar rate it at up to 30 rounds per second, and it can run in closed-bolt or AEG mode.

Programmable FCU

The fire control unit lets you assign semi, full auto or a 2 to 9 round burst to each selector position. You can also set a rate-of-fire limit, adjust dwell timings, and enable an anti-stiction pulse for cold-weather play. All settings are made with the button on the FCU.

Strike regulator and line

The Strike regulator adjusts from 0 to 210 PSI and has a clear gauge, so you can set and check your pressure at a glance. It is supplied with the Strike 40″ Flexy line, which is braided, rated to 280 PSI and fitted with US QD connectors.

This kit is for AK owners ready to move from a standard AEG to HPA, for its improved trigger response, consistency and fine control over their rifle's performance. Installation needs some technical confidence; if you are new to gearbox work, we recommend having it fitted by a tech. To complete your HPA setup, browse our HPA tanks and accessories, 7.4v LiPo batteries and the full PolarStar range.
