PolarStar F2™ Offset HPA Conversion Kit
The first true closed bolt offset HPA conversion kit on the market. The F2™ Offset shares the same rear cylinder, poppet valve, and internals as the standard F2™, with a redesigned front cylinder that accommodates offset nozzle configurations for rifles where a center-line nozzle won't work. PolarStar Filter Fitting included.
Its front cylinder features dual pin tracks accepting nozzle tips offset to either the top or bottom — broader compatibility without additional components. The two-piece offset nozzle uses a stainless steel support pin to stabilize the longer nozzle and prevent vertical movement, ensuring consistent BB seating and higher accuracy.
Same dual solenoid design as the F2™: independently adjustable nozzle and poppet valve, true closed bolt or "AEG" firing mode, one-piece lightweight poppet valve, spring-biased forward nozzle, and the full 45–145psi operating pressure range.
