The Geissele CHF Chrome Lined 5.56 11.5" Barrel brings Geissele’s proven barrel technology to compact AR-15 builds. This cold hammer forged chrome moly vanadium barrel uses an enhanced taper profile and chrome-lined bore to deliver a balance of rigidity, longevity, and consistent accuracy in a short 11.5 inch package. A carbine-length gas system, M4 feed ramps, and 1/2x28 threaded muzzle make it ready for modern AR configurations.

This 5.56 NATO barrel is well suited for duty-style rifles, defensive carbines, and high-volume training builds where reliability and barrel life matter. The 1:7 twist rate stabilizes a wide range of bullet weights, while the manganese phosphate exterior finish and chrome-lined interior help resist wear and corrosion over extended use. Built to Geissele’s exacting standards and individually HPT/MPI tested, this barrel reflects the brand’s reputation for precision machining and durable components.
