Lantac Reacon Upper 300 Bo 16

The Lantac Reacon Upper 300 Bo 16 is a precision-engineered upper receiver assembly designed specifically for .300 Blackout operators who require suppressed fire capability. This 16-inch upper is ideal for tactical applications where subsonic performance, modularity, and reliability are essential, making it suitable for law enforcement, military special operations, and civilian tactical shooters.

Constructed from precision 4140 steel, the upper features tight tolerances and optimized gas port geometry to ensure reliable cycling of .300 Blackout ammunition across both subsonic and supersonic loads. Weighing 4.75 pounds, it strikes a balance between mass and ergonomic handling, providing enough weight to manage recoil impulse while remaining light enough for tactical mobility.

This upper receiver integrates seamlessly with any mil-spec AR-15 lower receiver, making it a versatile choice for various users. While it offers the potential for sub-MOA accuracy when paired with quality ammunition and a properly tuned lower receiver, it is particularly beneficial for close-quarters operations where sound signature control is critical.
