Features
Brownells government barrel assemblies are produced by a US government contractor specifically for M4 barrels and adhere to rigorous standards. These barrels come with a hard chrome bore applied over button rifling and undergo a series of tests, including high-pressure testing, magnetic particle inspection and gauging, ensuring no imperfections. Ready for installation, the assemblies feature a slip ring assembly, non-marked front sight base and handguard cap pre-installed. The handguard caps are tailored to the barrel length, with M4 Carbine assemblies receiving a round cap and rifle length barrels receiving a triangle cap. Made from 4150 chrome moly steel, these barrels have a 5.56x45mm chamber and a 1:7 twist rate, offering reliable performance with 62 grain and heavier bullets. All components, including barrel extensions and front sights, are sourced from trusted US-based suppliers in compliance with mil-spec standards.
