The Aimpoint LPI, IR Laser Aiming Device is an active aiming device or target designator for military and Law Enforcement applications in darkness or poor light conditions. It is a development based on long experience in engineering and manufacturing of lasers ranging from pistol to military infantry rifle applications. The Aimpoint LPI is intended as a complement to the passive aiming systems from Aimpoint. It is designed to fit directly on an Aimpoint red dot sight, which means that no special rail system is required.
