Begadi barrel spring / HopUp spring, iridescent (long version, 31mm)
Begadi running spring / HopUp spring for (S)AEG models.
This spring is needed on many (S)AEG models to press the HopUp unit against the gearbox. If the spring is too weak, it can lead to pressure loss between the nozzle and the HopUp rubber. We offer this spring in two lengths, please check which length is suitable for your gun.
This spring is also needed for the Retro Arms Gen.2 HopUp Unit.
