Criterion Barrels CORE Chrome Lined .223 Wylde AR-15 Barrel - Carbine - Tapered - 10.5"

The Criterion Barrels CORE .223 Wylde AR-15 Barrel with a 10.5" length and carbine gas system is engineered for tactical shooters who demand a balance of performance, handling, and durability. The continuous taper profile redistributes steel around the chamber to absorb heat evenly and shift the rifle's balance closer to the body for greater control with optics, suppressors, and lights.

Features:

• 10.5" barrel, continuous taper profile
• .223 Wylde chamber (fires 5.56 NATO and .223 Rem)
• 4150 CrMoV steel construction
• Chrome-lined bore, phosphate finish
• Honed and hand-lapped 6-groove rifling, polished chamber
• Tuned gas port for suppressed and unsuppressed use
• Carbine-length gas system
• .625" gas block journal with dimple
• Threaded 1/2x28
• 1:8 twist
• Precision-machined barrel extension with M4 feed ramps

The chrome-lined bore enhances longevity and corrosion resistance without sacrificing accuracy, while honed and hand-lapped rifling ensures uniformity, precision, and ease of cleaning. The finely polished .223 Wylde chamber allows safe, accurate use of both .223 Remington and 5.56 NATO ammunition, and the tuned gas port supports reliable cycling whether run suppressed or unsuppressed.

Criterion Barrels builds high-quality, precision AR-15 and AR-10 barrels, as well as barrels for legacy platforms like the M1 Garand, M14, and Lee Enfield. Their barrels are used by the US Army Marksmanship Unit Action Shooting Team and the US Marine Corps Combat Shooting Team, proven to win matches time and time again.
