The Radical Firearms 16-inch SOCOM-profile barrel is built for dependable AR-15 performance with a mid-length gas system and a fast 1:7 twist suitable for a wide range of .223/5.56 ammunition. Machined from durable 41V50 chrome moly vanadium steel and treated with a corrosion-resistant Melonite finish, it delivers excellent wear resistance with a bore that’s harder than traditional chrome lining, without the typical accuracy tradeoffs. Ideal for a new build or upgrading an existing rifle, this barrel is chambered in 5.56 NATO and features M4 feed ramps for reliable feeding.
