The Mk4 Weapon-Mounted Tactical Light from Steiner, Inc features a stunning 500 Lumen LED output in a sleek, compact package. The Mk4 mounts to any MIL-STD-1913/Picatinny Rail using a low profile thumbscrew mount that neatly tucks the light in between the top and side rails of an M4/M16/AR15 rifle.
The ultra-high output 500 Lumen Mk4 is recoil-resistant and designed to be weapon mounted during sustained fire. The Total Internal Reflective (TIR) head produces a brilliant beam, able to easily blind adversaries while pushing white light out to 300 meters! The tailcap assembly offers two modes of operation: push button or remote switch. If the operator elects to not use the remote switch, it can be removed. The Mk4 meets MIL-STD-810G Testing Standards.
White light is an incredibly important aspect of low light/no light operations: the brighter, the better. Effective use of white light increases operator safety. Brighter lights can aid in searching and open areas and help operators prevail in CQB situations. The Mk4 is one of the most effective white lights for long guns.
