The biggest complaint we hear about the Surefire X300 series lights is the switch being too difficult to activate.
We have come up with a reliable solution to alleviate this issue, using a modified door to perform with far less pressure required to activate the toggle switch.
These switches feel very much like the popular Streamlight TLR series once completed, just slightly more stiff to prevent AD's.
We use only authentic Surefire battery door assemblies that are brand new.
Z-XBC doors are compatible with SureFire X300, X400 and XH30 WeaponLights (Not compatible with the XH50G)
