Surefire M640df Sct Pro 1500 Bk Blem

The Surefire M640DF Scout Pro is a 1500-lumen tactical flashlight purpose-built for weapon-mounted applications in law enforcement, military, and defensive settings. This model delivers the output and runtime characteristics operators depend on when absolute light discipline and raw illumination matter in close-quarters environments.

The M640DF produces 1500 lumens from a compact form factor optimized for carbine and long-gun mounting via its integrated 1913 Picatinny rail interface. The included Z68 on/off tailcap provides momentary and constant-on capability, essential for tactical searching and target identification under stress. The SF18650B rechargeable battery with micro-USB charging eliminates dependency on disposable cells during extended training or operational deployments. Weight of 0.75 lbs keeps the assembly balanced and minimizes shift on rifle-mounted systems. An included M-LOK mounting option broadens platform compatibility beyond Picatinny rails.

This Scout Pro variant serves shooters who require a dedicated light for tactical rifle work, home defense carbines, and close-range engagement scenarios where the user maintains one-handed weapon control while deploying illumination. The 1500-lumen output penetrates intermediate distances effectively without overexposing tight indoor spaces common to structure-clearing and low-light response. The modular mounting system—shipping with both Picatinny and M-LOK options—adapts to AR platforms, AK-pattern rifles, and other modern long-gun configurations.

This listing reflects a blemished unit: original packaging shows cosmetic damage, but the flashlight itself is fully functional and carries the same specifications and performance as new retail stock. For buyers prioritizing capability over pristine packaging, the blem price point delivers significant savings on a proven combat-rated light system.
