Carry in confidence and identify targets quickly and effectively with the Nightstick® Compact Tactical Weapon-Mounted Light. The 550-lumen max output, coupled with a precision-engineered total internal reflection (TIR) lens, creates a bright white beam out to 136 meters for reliable target identification. This lightweight weapon light boasts a streamlined, low profile for a quick and smooth draw. Ambidextrous and intuitive rear-facing toggle switches on each side of the light work well with both right- and left-handed shooters, while momentary-on and constant-on lighting modes afford you complete control over your light discipline. The 6061-T6 aircraft aluminum front housing and polymer rear housing delivers exceptional durability and shock resistance. Includes 4 handgun-specific modular rail inserts (pre-configured with C1 insert for Glock pistols), 2 spare Allen screws, an Allen wrench, and one CR123 Lithium battery.
