Sons of Liberty Gun Works Liberty Fighting Chrome Lined .223 Wylde AR-15 Barrel - Carbine - Medium - 11.5"

Short barrels demand reliable barrels. The Sons of Liberty Gun Works Liberty Fighting Barrel in 11.5" carbine-length is built to handle the increased fouling, higher cyclic rates, and thermal demands that come with compact AR-15 configurations.

Features:

• 11.5" barrel, 5R rifling, button rifled
• .223 Wylde chamber (fires 5.56 NATO and .223 Rem)
• 41V50 chrome moly steel construction
• Chrome-lined bore, phosphate exterior finish
• DLC-coated barrel extension
• Carbine-length gas system
• .750" gas block journal with deep dimple
• Threaded 1/2x28
• 1:7 twist
• 21.5 oz weight

The .223 Wylde chamber accepts both 5.56 NATO and .223 Rem ammunition without the pressure concerns of a 5.56 chamber or the accuracy limitations of a .223 Rem chamber, making it a versatile choice for a fighting barrel. Chrome lining resists corrosion and erosion under high-volume use, 5R rifling reduces bullet deformation and fouling compared to traditional 6-groove rifling, and the DLC-coated barrel extension adds a low-friction, hard-wearing surface at the bolt-to-barrel interface. Compatible with mil-spec AR-15 lowers and carbine-length gas systems, this barrel suits short-barreled configurations, duty builds, and compact patrol rifles.

Sons of Liberty Gun Works is known for building no-compromise AR-15 components trusted by armed professionals and serious civilian shooters. Made in the USA, and backed by the standard SOLGW warranty.
