Aluminum Airsoft AEG Cylinder Head G36C w/ Double O-Ring Made in Taiwan

The Action Army G36 Cylinder Head is made from high quality Aluminum and is designed to fit the G36 gearbox. The Action Army series of upgrade parts are compatible with most major brands of AEG such as Tokyo Marui G&G ICS VFC KWA H&K JG SRC UMAREX Class Army Echo 1. Action Army is providing a cylinder head with 2 o-rings instead of just one. The extra o-ring provides a much better seal against the cylinder for maximum compression.
