The Holosun LS321G is the multi-laser aiming device that gives serious rifle and PDW users the complete active aiming solution in a single compact rail-mounted package - combining a visible green laser, IR laser, and IR illuminator in a co-axial housing that simplifies zeroing and delivers reliable tri-function laser performance in a rugged 7075 aluminum body built for hard field use. The defining feature of the LS321G is the co-axial mounting of all three laser and illuminator components - the visible green laser, Class 2M IR laser, and IR illuminator are all mounted on the same optical axis, which means zeroing the visible green laser in daylight effectively zeros all three aiming solutions simultaneously. For shooters who have experienced the frustration of zeroing multiple separately mounted laser and illuminator devices, the Holosun LS321G Coaxial Green co-axial design eliminates that multi-step zeroing process entirely and replaces it with a single simple daylight zeroing procedure that transfers directly to the IR laser and illuminator without any additional adjustment. The Holosun LS321G Class IIIA visible green laser provides a bright, immediately visible aiming point in daylight and transitional lighting conditions where red lasers are less visible - green laser wavelength is naturally more visible to the human eye across a wider range of ambient lighting conditions. The Class 2M IR laser provides the invisible aiming point that night vision device users specifically need for covert targeting capability, and the IR illuminator provides active illumination that extends the effective range and image quality of night vision equipment in low ambient IR environments. The LS321G quick release Picatinny rail mount allows fast, tool-free attachment and removal from any standard Picatinny rail-equipped rifle or PDW. The IP67 water resistance rating ensures reliable operation through rain, moisture, and immersion conditions that field use regularly produces.
