G&PxPolar Star exciting new product!

Offical Polar Star HPA electro-pneumatic system + all G&P custom HPA parts! Polar Star is a USA company (since 2009) known for their widely successful "Fusion Engine" that converts standard AEGs into an HPA (High Pressure Air) system that's electro-pneumatically driven! These run on an external air tank instead of batteries or propane type gas. It is a top of the line HPA system! Polar Star make 3 products that can make the conversion, the Polar Star Jack, F1, and their top of the line product, the Fusion Engine. G&P's release utilizes the Jack that replaces all analog/mechanical parts inside the gearbox, replacing the Cylinder/Piston set while keeping the V2 gearbox shell. This system provides amazing features that are easily & quickly programmable via a Fire Control Unit! All systems are customizable from FPS, Burst & Rate of Fire that can range from a 1 rps to an insane 50+ rps!! Trigger response is also better like GBB! This system is very stable under a wide weather & temperature conditions with very stable FPS shooting thanks to its electro-pneumatic system. It is low maintenance & quick programming too!
