Arisaka OSM-P Type Offset Scout Mount for 20mm Rail

The Arisaka OSM P-Type 45° Offset Scout Mount revolutionizes tactical setups by enabling precise side-mounted placement of scout lights or laser indicators on 20mm Picatinny rails. Crafted from aircraft-grade 6061-T6 aluminum with a hard-anodized finish, this mount withstands rugged use while maintaining a lightweight profile (120g) for minimal weapon bulk. The 45° offset design ensures optimal positioning for quick target acquisition in close-quarters combat, avoiding obstruction of primary optics. Featuring a tool-free quick-detach mechanism, it installs/removes in seconds, ideal for dynamic mission requirements. The precision-machined interface ensures zero retention, while anti-slip serrations prevent light shift during recoil. Perfect for military, law enforcement, and competitive shooting, this mount balances durability with ergonomic design—enhancing situational awareness by integrating auxiliary equipment without compromising weapon handling. Trust Arisaka’s tactical engineering for reliable, battle-proven performance.
