Interior of the replica
nrg equips this replica with the F2 conversion system manufactured by Polarstar. This is a compressed air or HPA system designed for converting electric-powered replicas. The dual solenoid design of the F2 model offers the same functionality as the legendary Fusion Engine, but in a more compact, flexible, and efficient design. The F2 model comes with a new valve design that operates on the same principle as that of the Fusion Engine. This valve can operate at lower pressures and uses a smaller volume of air to function, optimizing air efficiency. This engine allows for a pressure range from 45 psi to 145 psi, enabling it to cover multiple power classes, from low power for close-quarter battles to DMR-type replica powers. Another advantage of this engine is the ability to choose the nozzle position, between closed bolt and open bolt, similar to AEGs.
Power Supply
The package includes an HPA air regulator provided by Polarstar model MRS. This regulator combines all the technologies used so far by Polarstar to provide users with the best experience. It is equipped with all the important systems such as a manometer and tournament lock. Additionally, the package includes a hose manufactured by Polarstar designed for HPA systems. This extremely flexible hose is made of rubber and is covered with a braided nylon material, thus reducing the risk of damage or tangling. The hose is delivered with US-type QD fittings.
Attention!!
The package does not include an HPA tank or battery.
