Description
AIRTECH AEG Spring Spacers are a small internal component intended to sit behind the spring inside an airsoft AEG gearbox and alter its preload. Changing the amount of spacing behind the spring affects how far it is compressed when the gearbox is at rest, which allows the same spring to be set up for a higher or lower FPS figure depending on what you are trying to achieve.
This version follows the Tokyo Marui specification and is listed as suitable for universal AEGs built to that standard. It is a straightforward part for anyone already comfortable opening a gearbox and looking to make fine adjustments to power output without moving to a different spring.
As with any internal part, fitment should be checked before assembly, and the resulting energy should be tested once installation is complete.
