The Geissele Automatics Geissele CHF Chrome Lined 5.56 16" barrel is a cold hammer forged AR-15 barrel built for shooters who demand consistent accuracy and long service life. Crafted from chrome moly vanadium steel with Geissele’s taper profile, this 16-inch barrel uses a mid-length gas system, M4 feed ramps, and a chrome-lined bore to balance reliability, recoil impulse, and durability for hard-use rifles.

This model is chambered in 5.56 NATO with a 1:7 twist rate and 1/2x28 threaded muzzle, making it ready for a wide range of muzzle devices or suppressor mounts. The .750 gas block journal and carefully sized .078 gas port support smooth cycling across a variety of loads, whether you are building a duty-ready carbine, a competition rifle, or a dependable training setup. Geissele’s reputation for precision machining and rigorous HPT/MPI inspection underscores the quality of every barrel they produce.
