The Viridian R5 Gen 2 green laser sighting system for the Remington RM380. This laser sight is easy to install and blends seamlessly into the trigger guard for invisible profile and smooth draw. Viridian's green lasers utilize a 510 to 532 nm wavelength range creating an optimum target dot that is up to 50 times brighter than red lasers. It features two modes of operation: constant and strobe. New features of the gen 2 models include 3X more battery life (up to 5 hr) and an instant-on ambidextrous, inside the waistband (IWB) holster with automatic laser activation. Made of microfiber, this holster is more comfortable and durable than the previous models. The instant-on activation ignites the laser the moment you draw. No buttons, no squeezing, no doubt. When you draw, it's on.
