Steiner Optics designed the desert sand CQBL-1 Close Quarters Battle Visible/IR Laser Sight as a durable yet compact 24/7 aiming device that combines red visible and infrared aiming lasers. Its 850nm infrared laser is visible with NVDs up to 273 yards away, and the red has a max range of 16' during the day or 273 yards at night. The CQBL-1's two laser are co-aligned to allow the operator to zero or correct the impact point of both lasers simultaneously using the finger-adjustable windage/elevation dials. The dials, laser selector switch, and activation button are all recessed to eliminate snag points and reduce the sight's overall profile.
