Geissele Automatics Ar-15 14.5'' Chf Chrome Lined Barrel 5.56Mm

The Geissele Automatics AR-15 14.5" CHF Chrome Lined Barrel in 5.56mm is a cold hammer forged precision barrel built for shooters who demand reliability under real-world conditions. Whether you're running a duty rifle, building a suppressed SBR, or tuning a competition gun, this mid-length gas tube barrel delivers the accuracy and longevity that separates quality uppers from the rest. Geissele manufactures their barrels in-house at their North Wales, PA facility using cold hammer forging and high-quality chrome molly steel, then subjects each one to high pressure testing (HPT) and magnetic particle inspection (MPI) to catch any defects before it ships.

The chrome lined bore is a genuine advantage if you plan to shoot corrosive ammunition, run suppressed, or simply want a barrel that will handle thousands of rounds without accelerated wear. The 1/7 twist rate is the modern standard for 5.56, handling everything from lightweight varmint rounds to 77-grain match ammo without issue. You get government profile dimensions with a single dimple for reliable gas block set screw purchase—no guessing, no slop.

At 14.5" with mid-length gas system tuning, this barrel strikes the balance between velocity and maneuverability that works for carbines destined for close-quarters use, suppressors, or both. The 1/2 x 28 threading accepts any standard AR muzzle device. If you've built enough rifles to know that barrel quality matters, or you're tired of chasing accuracy and reliability issues with budget parts, this is the no-compromise choice.
