Our take: This SHS X-Mod M100 Airsoft upgrade spring is made for most-all Airsoft metal gearbox AEGs. Constructed of tempered high-carbon steel wire with a variable pitch, it is one of the best ways to adjust the FPS output of your metal gearbox AEG. High quality, low price tag. This is a perfect spring for any AEG, boosting the FPS higher than the stock spring. It is highly recommended when installing an upgraded spring to also install an upgraded metal spring guide and metal bushings. FPS rating: 320-340 FPS with .20g BB's
