I have found that the lower inner barrel length the more fps you use for example i run a madbull 229mm inner barrel at 6.0 diameter and with a blue nozzle at 120psi im only achieving 260 fps with a .20g bb so in order to get the target fps i was looking for was 300 with a .25 i had to buy two different nozzles so just keep that in mind when you buy nozzles i just wish i knew that before i ordered my engine so i could at least buy all the nozzles with it just a heads up but other than that it works fantastic :) very pleased with my polarstar
Drops right in dont have to remove the entire fusion engine to swap out nozzles
Barrel length affects your fps tremendously even with the poppet dwell high
