Sons of Liberty Gun Works Liberty Fighting .223 Wylde CL Mid-Length - AR-15 Barrel - 13.7"

Mid-length gas at a length that keeps an AR-15 light, fast, and reliable. The Sons of Liberty Gun Works Liberty Fighting Barrel in 13.7-inch gives you a .223 Wylde chamber, 5R rifling, and a chrome-lined bore on a mid-length gas system — a combination that delivers smoother cycling, reduced felt recoil, and longer barrel life than an equivalent carbine-length configuration.

The Sons of Liberty Gun Works Liberty Fighting Barrel is a 13.7-inch 5R-rifled AR-15 barrel chambered in .223 Wylde, built from 41v50 chrome moly steel with a chrome-lined bore and phosphate exterior, operating on a mid-length gas system for enhanced cycling characteristics over carbine-length equivalents.

Four specifications define the Liberty Fighting Barrel's performance advantage. The .223 Wylde chamber handles both 5.56 NATO and .223 Rem ammunition without pressure or accuracy compromise, giving this barrel maximum ammunition flexibility for training and duty use. Chrome lining in the bore resists corrosion and erosion under sustained fire, extending barrel life and reducing the bore maintenance required in field conditions. 5R rifling reduces bullet deformation and fouling accumulation compared to traditional 6-groove designs, supporting consistent accuracy across a wide range of projectile weights. The DLC-coated barrel extension provides a hard, low-friction surface at the bolt-to-barrel interface that holds up to the wear of a high-round-count fighting rifle.

Compatible with mil-spec AR-15 lowers and mid-length gas systems. .750-inch gas block journal with deep dimple. 1/2x28 threaded muzzle.

41v50 chrome moly steel, button rifled. Chrome-lined bore, phosphate exterior. 1:7 twist. 24.8 oz.

Built for duty AR-15 configurations, patrol rifles, and training builds where a mid-length gas system, .223 Wylde chamber, and chrome-lined bore deliver fighting-rifle reliability at a practical barrel length.
