HPA Conversion Kit F2™ V2 for M4/M16 - PolarStar

PolarStar F2™ V2 HPA Conversion Kit for M4/M16 is an advanced solution for converting airsoft rifles such as M4, AR15, ARP, SCAR-L and other V2 gearbox platforms into a high-performance pneumatic system. This compact HPA unit delivers performance comparable to the Fusion Engine while offering a smaller and more flexible design.

Thanks to its patented dual-solenoid system, it allows independent adjustment of the nozzle and poppet valve, providing precise control over air volume and BB feeding. The spring-loaded nozzle ensures consistent feeding force across different operating pressures. The system supports both closed-bolt and open-bolt operation modes and offers a wide performance range for fine tuning according to gameplay requirements.

The aluminum construction ensures durability while maintaining low weight. With broad compatibility and interchangeable nozzles, this HPA system is an ideal choice for demanding players seeking maximum performance, consistency, and precision.
