Criterion Barrels AR-15 CORE Series .223 Wylde Barrel - 20" - Rifle Length - Chrome Lined - Phosphate - 1:8 - 20"

The Criterion CORE Series 20" barrel is a precision component for AR-15 platforms, designed to enhance balance, handling, and sustained performance. Featuring a continuous taper profile, this barrel shifts weight distribution toward the chamber, improving heat absorption under heavy use and maintaining optimal rifle control with accessories mounted. The .223 Wylde chamber provides compatibility with both .223 Remington and 5.56 NATO cartridges while offering increased accuracy through stabilized chamber pressures. The 4150 CrMoV steel construction is chrome-lined for long-term durability and corrosion resistance without compromising precision. A rifle-length gas system, polished chamber, and hand-lapped rifling support reliable cycling and consistent extraction. Made in the USA.
