Lantac Reacon Upper 300 Bo 16

The Lantac Reacon Upper 300 Bo 16 is a precision-engineered upper receiver assembly purpose-built for .300 Blackout operators who demand suppressed fire capability without compromise. This 16-inch upper is specifically designed for tactical applications where subsonic performance, modularity, and reliability are non-negotiable—making it ideal for law enforcement, military special operations, and civilian tactical shooters. The compact 31.25-inch overall length combined with the inherent subsonic ballistics of the .300 Blackout cartridge positions this upper as a go-to choice for close-quarters operations where velocity management and sound signature control matter.

LanTac's Reacon upper leverages precision 4140 steel construction with tight tolerances and optimized gas port geometry to cycle .300 Blackout ammunition reliably across subsonic and supersonic loads. Weighing 4.75 pounds, the upper strikes a balance between mass and ergonomic handling—heavy enough to manage recoil impulse and reduce muzzle rise, yet light enough for tactical mobility and weapon-mounted accessory compatibility. The 16-inch barrel provides the velocity optimization point for .300 Blackout ballistics while maintaining a compact profile; this configuration delivers sub-MOA accuracy potential when paired with quality ammunition and a properly tuned lower receiver with appropriate buffer system.

This upper receiver integrates seamlessly with any mil-spec AR-15 lower receiver, making it compatible with standard buffer tubes, stocks, and fire control groups—no special tools or modifications required during installation. Operators running suppressed .300 Blackout systems will appreciate the caliber's natural subsonic capability, which pairs exceptionally well with modern sound suppressors; supersonic loads remain viable for unsuppressed fire when mission parameters change. The Lantac Reacon Upper 300 Bo 16 suits precision rifle builds, entry/breach platforms, and dedicated subsonic duty systems for trained tactical operators who understand .300 Blackout ballistics and ammunition selection.
