Faxon Firearms Combat Series 5.56 NATO 14.5" 1:8 Twist Medium Taper AR-15 Barrel - Chrome Lined

The Faxon Firearms Combat Series barrel is a hard-use drop-in for AR-15 builds chambered in 5.56 NATO. Machined from 4150 chrome moly vanadium steel with a chrome-lined bore and a phosphate exterior, this 14.5" barrel is built to take abuse while still holding tight groups.

The Medium Taper profile keeps the barrel light enough for a well-balanced carbine while retaining rigidity at the chamber. Button rifled with a 1:8 twist, it stabilizes a wide range of 5.56 NATO bullet weights from light varmint loads to heavier 77-grain openers. The barrel is set up for a carbine-length gas system and uses the standard 1/2x28 thread pitch for muzzle devices, with an M4 barrel extension.

As part of the Combat Series, this barrel is purpose-built for duty, training, and defensive rifles where reliability and ease of cleaning matter as much as accuracy. The chrome-lined bore resists corrosion and heat erosion while extending service life, and the phosphate finish provides a durable, low-glare exterior. Made in the USA by Faxon Firearms.
