Core .223 Wylde 16'' 1-8 Tapered Mid-length Chrome-lined Thrd

The Criterion Barrels Core .223 Wylde 16" 1-8 Tapered Mid-length Chrome-lined barrel is a precision-engineered upper receiver component designed for law enforcement, military, and serious civilian marksmen who demand accuracy and reliability in modular rifle builds. Built on the time-tested AR-15 platform, this barrel bridges the gap between close-quarters defensive applications and mid-range precision shooting, making it an ideal choice for patrol carbines, competition builds, and duty rifles.

Manufactured by Criterion Barrels Inc—a recognized OEM supplier for military and law enforcement—this barrel features a chrome-lined bore for extended service life and corrosion resistance in harsh environments. The 1-8" twist rate stabilizes modern 5.56 NATO and .223 Remington projectiles ranging from 55-grain varmint rounds to heavier 77-grain match ammunition, ensuring versatility across mission profiles. At 16 inches, the mid-length gas system provides balanced ejection reliability and controllability, while the tapered profile reduces front-end weight without sacrificing structural integrity. The 1/2x28 threaded muzzle accepts standard AR suppressors, flash hiders, and muzzle devices, and the black nitride finish resists wear and corrosion during field deployment.

This barrel is ideal for shooters building or upgrading complete AR-15 rifles for duty, training, or sport use. Installation requires standard upper receiver assembly tools and basic gunsmithing knowledge—the threaded profile integrates seamlessly with mil-spec AR-15 uppers and bolt carrier groups. At 1.7 pounds, the tapered design reduces reciprocating mass compared to heavier barrels, improving handling and reducing fatigue during extended shooting sessions. Whether you're running this as a patrol carbine, three-gun competition platform, or precision training barrel, Criterion's Core line delivers field-proven accuracy and reliability at a professional level.
