The Holsun LE321R / LE321G is a titanium-bodied multi-laser aiming device that includes a Class 2M IR laser, Class IIIA visible red laser ("R" model) or green laser ("G" model), IR illuminator and a 300 lumen white light. Perfect for platforms where rail space is limited or if weight is a concern, the LE321 has an extremely small and lightweight footprint for a device with so many features. The IR laser, visible laser, and IR illuminator are all aligned together - zeroing one means all three are zeroed. The width of the IR illuminator flood is adjustable via a knob on the back of the laser. The device has the following modes on-board: IR laser Low IR laser High IR Illum only Low IR Illum only High Visible laser Low Visible Laser High White Light Low Visible Laser & White Light Low Visible Laser & White Light High IR Illuminator High & IR laser Low Featuring a quick-detach throw-lever mount, 2 built-in recoil lugs, remote pressure switch and port that accepts common L3/Crane style laser plugs, the LE321 also offers IPX8 water resistance for the ultimate in reliability.
