Surefire puts the spotlight on their Surefire Scout Light Pro in this video... "SureFire’s legendary Scout Light® WeaponLights have proven themselves in combat around the world. Our new Scout Light Pro family builds on this success with an integrated next-generation mounting system that offers the ultimate in versatility for long gun weapon light users. Every Scout Light Pro features our new Low-Profile Mount (LPM), allowing the user to mount their light as close to the weapon no matter the rail or configuration. The LPM affords tremendous flexibility when used in conjunction with a variety of rail profiles or accessories; simply pivot the WeaponLight body to allow optimal light positioning, then lock it down securely with any flat blade screwdriver or multi-tool. All Scout Light Pros will ship with both a MIL-STD-1913 mount as well as an M-LOK® mount."
