If you want a high strength, low friction cylinder for your Tokyo Marui M40A5 style rifle look no further. This includes the cylinder head and the back is securely pinned in place. An essential upgrade if your rifle's cylinder is showing it's age or upgrading the power!
Some technical skill is required to fit these, mis-fitting will invalidate your warranty. We strongly advise using a proper cylinder tool to remove and replace the cylinder head.
If you are not confident in your ability to fit this or you do not have the appropriate tools please contact us and we can arrange to have it fitted for you for a small fee.
