Description
Balanced, lightweight, and suppression-friendly — the sweet spot for compact carbines.
The Faxon Duty Series 12.5″ Gunner Profile 5.56 NATO barrel blends two proven contours — Government and Pencil — to deliver strength where it matters and weight savings where it counts. Built in-house from certified 4150 CMV and finished black nitride inside and out, this mid-length gas barrel provides smooth timing, excellent balance, and repeatable accuracy in a compact package.
- Balanced Gunner contour: Government strength behind the gas block with Pencil-style weight savings forward for quick handling and reduced fatigue.
- Mid-length gas reliability: 12.5″ with mid-length gas offers smoother cycling and easier tuning (suppressed or unsuppressed) than shorter systems.
- Duty-grade materials: Certified 4150 CMV, button-rifled 1:8 twist, and black nitride finish for longevity and corrosion resistance.
- Accuracy-focused: Fully stress relieved, air-gauge tested, MPI, and finished with an 11° target crown.
- Build-friendly interface: Standard 1/2-28 muzzle threads and .625″ gas block journal (1.9″ length) for broad compatibility.
- In-house QC: Individually headspace-checked with precision gauges before it leaves our Cincinnati facility.
