Lantac Patrol Upper 300 Bo 11.5

The Lantac Patrol Upper 300 Bo 11.5 is a complete AR-15 upper receiver assembly chambered in 300 Blackout, engineered for shooters who demand reliability in compact tactical platforms. Built for law enforcement, military, and civilian operators requiring suppressor-ready configurations in confined spaces, this upper combines professional-grade construction with the proven ballistic advantages of subsonic 300 Blackout ammunition. The 11.5-inch barrel length provides optimal velocity and control for close-quarters work while maintaining the modularity that AR-15 users expect.

This Lantac patrol upper receiver features precision machining in 7075-T6 aluminum with a matte anodized finish that resists corrosion and reduces glint in tactical environments. The complete upper assembly integrates the bolt carrier group, charging handle, and barrel into a ready-to-install package that requires only mating to a compatible lower receiver—eliminating the need for individual component sourcing and assembly. At 0.81 pounds, the upper delivers lightweight handling without sacrificing structural integrity, critical for operators managing extended deployments or dynamic room-clearing scenarios where weapon fatigue directly impacts accuracy and target acquisition speed.

The Lantac Patrol Upper 300 Bo 11.5 is ideal for shooters building or upgrading suppressed AR-15 systems, where the subsonic 300 Blackout cartridge minimizes supersonic crack and maximizes sound reduction when paired with quality suppressors. Its 11.5-inch configuration suits short-barreled rifle (SBR) builds, pistol caliber carbine conversions, and close-quarters battle (CQB) platforms used in law enforcement and tactical training. Compatibility is assured across standard AR-15 pattern lower receivers, making this upper a drop-in solution for existing platforms or new builds seeking a field-proven, production-quality upper assembly.
