HPA Conversion Kit F2™ M249 - PolarStar

HPA Conversion Kit F2™ M249 - PolarStar The PolarStar F2™ M249 is an HPA engine designed for converting M249 airsoft replicas. The dual solenoid design allows independent control of the nozzle and valve, enabling precise adjustment of feeding timing and air flow.

The system supports both closed bolt operation and standard AEG mode. The new single-piece valve design is lightweight and optimized for lower pressure operation, reducing air consumption.

With an operating pressure range of 45–145 psi, it allows performance adjustment without changing the nozzle. The pre-loaded nozzle ensures consistent feeding regardless of pressure. It uses Fusion Engine™ compatible springs to adjust feeding force.

The F2™ provides a wide performance range and high rate of fire. It can reach up to approx. 480 fps with 0.20g BBs and up to 30 rounds per second. Efficient air usage allows over 1000 shots from a 13/3000 tank at 1.5J.
