Polarstar A&K/JG SR-25 Installation Spacer Kit
Description
Description
This spacer kit allows a V2 Fusion Engine to be used in the A&K and JG SR25 rifles. Since these models use an "V2 Long" gearbox, the standard V2 Fusion Engine will not be long enough to interface with the rifle's hop-up chamber and stock bolt. The included Delrin spacer extends the front of the engine so that it will be the correct length to match up to the hop-up chamber while the included Nut provides an anchoring point for the stock bolt.
Spacer kit allows for installation of V2 Fusion Engine using the A&K SR25/MASADA nozzle.
Includes delrin spacer with steel nut.
