Our take: This SHS X-Mod M170 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: 540-570 FPS with .20g BB's
SHS X-Mod Upgrade Part Series: An Airsoft Megastore Exclusive
The SHS X-Mod upgrade part series is an all-new line of SHS parts manufactured and distributed EXCLUSIVELY by Airsoft Megastore. The X-Mod series of parts are NOT to be confused with generic "SHS"parts currently on the marketplace, as the X-Mod parts are NOT BUILT THE SAME.
SHS is a leading performance part manufacturer, and Airsoft Megastore has engaged SHS directly to manufacture the X-Mod upgrade parts, which are now exclusively available at Airsoft Megastore.
The difference between SHS X-Mod parts and generic "SHS" parts currently in the marketplace is a noticeable improvement in consistency of quality and an improvement in build material. X-Mod parts are manufactured out of the latest and most advanced high performance materials with no shortcuts taken. X-Mod parts have been contracted by Airsoft Megastore to undergo a 12-point manufacturing quality assurance test (at every stage of the manufacturing process) to ensure sustained high quality.
The results are quite noticeable: SHS X-Mod parts consistently out-perform the competition, and are on-par with the highest quality upgrade parts available on the market, but at extremely competitive prices that won't break the bank.
Disclaimer: Any and all airsoft upgrade parts purchased from Airsoft Megastore will be used/installed at owner's discretion. We are not responsible for any damage that may occur. For best results, please have a professional airsoft Tech install all upgrade components at a certified professional airsoft technician/shop.
