Action Army Action Army L96 AWS Cylinder Kit. Fits on Tokyo Marui L96 AWS sniper rifles only. These are not for the Type 96 rifles that are Maruzen based. Kit includes the cylinder and cylinder head assembly.***Please note: The cylinder head and cylinder are custom threaded to work together in this kit only (it's a matched set). You cannot use an aftermarket cylinder head with this Action Army Cylinder. Only use the cylinder head this kit comes with. Even other Action Army heads will not work. The threads on the cylinder are not compatible with PDI, Laylax, etc. We've had complaints about this, so don't try to add a custom one.
