Warne 45 Degree Picatinny Mnt De

The Warne 45 Degree Picatinny Mount (Model A645 Side Mount) is a low-profile offset accessory rail designed for modern sporting rifles and tactical platforms equipped with flat-top receivers. This 45-degree angled mount attaches directly to Picatinny (MIL-STD-1913) rail systems and provides a secondary optics platform without requiring gunsmith work or permanent firearm modification. Its streamlined design makes it ideal for co-witnessing backup iron sights with primary optics mounted on upper receiver systems or custom rail setups.

The A645 uses a 45-degree angle to position secondary optics outside the primary sight line while maintaining rapid visual acquisition. Weighing only 0.13 pounds, the mount adds negligible mass to your platform. The integrated Picatinny interface ensures broad compatibility with ACOG mounts, red dot sights, magnified optics, and tactical lights designed to the military standard. The compact footprint—measuring 3.5 inches in length—accommodates tight handguard and rail real estate common on AR-pattern rifles, precision platforms, and purpose-built tactical chassis systems.

This accessory mount suits operators and shooters who require redundant sight systems, tactical trainers running multi-optic configurations, and precision rifle builders integrating secondary aiming solutions. The Warne A645 is a common choice for duty-rifle builds, law enforcement patrol rifles configured with both primary and backup magnification options, and competition shooters working offset sight setups. Installation takes minutes and requires no rail modifications, making it a practical upgrade for shooters testing different optic combinations without permanent alterations.
