Overview

Geissele CHF Chrome Lined AR-15 Barrel Features The Geissele CHF Chrome Lined AR-15 Barrel is cold hammer forged from chrome moly vanadium steel and chrome lined for superior bore wear resistance and corrosion protection across high-volume shooting and hard use duty conditions. HPT and MPI testing at the point of manufacture ensures every barrel meets the dimensional and structural standards required for reliable performance in a hard use AR-15 weapon system. Precision machining at Geissele s North Wales PA facility maintains the tight tolerances and consistency that define the CHF barrel lineup across duty competition and general-purpose AR-15 applications. The 5.56 CHF AR-15 barrel features a Geissele taper profile that balances weight reduction with the structural rigidity needed to maintain accuracy under sustained fire and hard use. A mid-length gas system .750 gas block diameter with a single set screw dimple and .076 gas port deliver a reliable tuned gas impulse across a wide range of 5.56 ammunition types and suppressed configurations. M4 feed ramps 1/2x28 muzzle threading and a 1-7 twist rate optimized for heavier 5.56 projectiles complete a purpose-built barrel ready for immediate installation on mil-spec AR-15 rifles.
