Surefire Scout Light Pro at 550 lumens in tan is exactly what I wanted for a duty carbine. Pic rail mount keeps it low profile. Tape switch wires through neatly. Tan body matches Magpul FDE parts. Throws further than the lumen rating suggests.
Surefires Scout Light Pro M340DFT in tan with the pic rail mount sits low on the handguard. 550 lumens at 12000 candela throws further than the lumen number suggests. Tape switch placement works at the 10 oclock position.
