Faxon 14.5" 5.56 NATO Gunner Barrel w/ Pinned Gas Block

Faxon 14.5″ 5.56 NATO Gunner Barrel w/ Pinned Gas Block

The Faxon 14.5″ 5.56 NATO Gunner Barrel w/ Pinned Gas Block offers an ideal balance of lightweight handling and heat resistance. Crafted from 4150 Chrome Moly Vanadium (CMV) steel, this barrel is finished in QPQ Nitride for enhanced durability, corrosion resistance, and ease of cleaning. Faxon manufactures each barrel in-house from gun-barrel-quality bar-stock and performs thorough headspace checks using precision-hardened gauges to ensure dependable performance.

Configured with a Mid-Length gas system, the 14.5″ Gunner Barrel features Faxon’s signature Gunner profile, combining the Government profile’s rear taper with a lightweight pencil contour up front. This fusion allows shooters to benefit from reduced front-end weight for improved maneuverability while maintaining rear-end strength to manage heat during rapid or sustained fire. It’s perfect for duty rifles, competitive builds, or lightweight configurations without compromising reliability.

To provide a secure, worry-free setup, the barrel comes with a pinned low-profile gas block, pre-drilled and notched specifically to match the barrel’s gas block journal. This ensures a rock-solid fit that won’t shift or loosen, even under hard use or suppressed conditions. It’s an excellent choice for shooters who want performance and peace of mind in a compact, suppressor-ready barrel.

Just what is the Gunner profile?

The Gunner profile blends the strength of the Government profile with the lightweight agility of the Pencil profile. From extension to journal, the taper mirrors the Government design, then transitions to a slimmed-down front end. This shift removes excess weight up front, improving control and responsiveness, while preserving thermal mass to the rear to handle sustained firing and reduce barrel whip.
