Our take: The new SHS X-Mod soft rubber piston head o-ring is made out of high quality rubber and is designed as a universal replacement for broken/cracked o-rings (often the cause of AEG performance issues due to lack of air-tight seal).
Compatibility: Fits most airsoft AEG piston heads
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. Actual performance results depend on quality of installation, airsoft AEG barrel length, tightness of the air nozzle seal, and other possible performance-affecting factors. We are not responsible for any damage that may occur with improper installation. For best results, please do all upgrades at a certified professional airsoft technician/shop.
