This replacement tailcap assembly includes the Surefire UE socketed tailcap and SR07 remote dual switch, which is compatible with any Surefire Scout M300 and M600 lights, plus the Arisaka 300 and 600 series lights.

The tailcap module screws onto any Scout light body, while the switch, cable, and connector are an integral unit. The entire unit is O-ring sealed at both ends, making it weatherproof.

The SR07 switch attaches to any 1913 Picatinny rail and features both momentary operation and constant-on with the dual switch design.
