Specifications
Why Choose the Gunner Profile
The Gunner profile brings the rifle’s balance point rearward, improving handling and reducing fatigue during long sessions on the range or in the field. Faxon’s design maintains the strength and heat resistance of a Government profile while eliminating unnecessary forward weight for faster transitions and better control.

- Use a .625" gas block on the 1.9" journal; adjustable models recommended for suppressor setups.
- 1/2-28 muzzle threads support brakes, comps, and direct-thread suppressor mounts.
- Perfect length for pin-and-weld builds to reach 16" OAL while maintaining excellent handling characteristics.

Quality workmanship
Matched this barrel with an Armalite upper/Rock River lower, fit was seamless. Fired standard 55g FMJ at 50yds. benched and had to bring the target back as the cloverleaf group looked like one hole w/naked eye. Well worth the money. Barrel taper is thin, light, and the balance is prefect. Very nice barrel.

Light weight and accurate
I only gave it 4 stars because I didn't throw on a high power scope and test it for groups but I was getting 1 inch groups at 75 yards with a red dot which is as good as any ar I have ever shot . Well done!

Great Barrel
Put this on a Anderson upper/lower, CMC trigger, Magpul/Troy furniture. Great bang for the buck. Highly recommend

Best barrel for the money!
First things first: This thing is SO lightweight! It's a pound lighter than some barrels. The gunner profile is very sleek as well. This barrel is very accurate as well! Throw in one of the micro gas blocks and it can't be beat!
