PolarStar Filter Fitting included

How does it work

the nozzle is only piloted by the solenoid to open air flow through the poppet with none of the firing air coming from the solenoid itself

This is made possible by its intelligently laid out design which minimizes dead volume resulting in better air flow

it is commonly known that you should not use CO2 to power an HPA engine since if liquid CO2 gets down-stream of the regulator it can cause a spike in pressure which is unsafe and can damage the sensitive components of the engine

M249 Hollow Grip Bolt and Nut JACK PolarStar Filter Fitting includedThis bolt and nut comes standard with our M249 series HPA engines and replaces the original grip bolt in your A&K or Classic Army M249 Mk46. The bolt being hollow allows the air line to pass through the center of the bolt so the air line can exit the replica through the grip instead of needing to drill a hole in the gun's body.
