Please note: As of August 2020, Surefire customer service says that the SR07 switch may not allow the M600DF to run at full brightness when using an 18650 cell.
This replacement tailcap assembly includes the Surefire DS 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 Surefire DS tailcap provides momentary operation with a slight press and constant on with a full click, plus has a remote switch port for use with the Surefire and TNVC/Unity TAPS remote switches.
The two piece, o-ring sealed design swivels to allow precise positioning of the switch and remote port.
The SR07 switch attaches to any 1913 Picatinny rail and features both momentary operation and constant-on with the dual switch design.
