The Holosun Multi-Laser Aiming Device LS321R is a professional lighting and aiming module designed for firearms. Equipped with a Picatinny rail mount, its compact size makes it ideal for use on rifles and submachine guns.

The device has two lasers – red and infrared – and an IR illuminator. Each laser offers two operating modes (low/high), while the illuminator allows for beam divergence adjustment.

The housing is made of anodized 7075-T6 aircraft-grade aluminum, providing high resistance to mechanical damage and shock while maintaining a low weight. An ergonomic switch makes operation easy, even when wearing gloves.

Power is supplied by one CR123A battery (not included).

The set includes:

• LS321R module
• switch with Picatinny rail mounting and hard Velcro panel
• self-adhesive panel with soft Velcro
• Torx Allen key
• microfiber cloth
• carrying case
