DUTY 5.56X45 NATO GUNNER PROFILE RIFLE BARRELS FOR AR-15 Reviews & Ratings

The Faxon GUNNER line of AR barrels are well known in the AR world for their unique profile. The GUNNER profile uses the Government profile dimension from extension to the .625” gas block, then is a pencil profile from the gas block forward to the front.

Removing the weight from the front of the barrel ensures maximum versatility and keeps material to the rear to maximize heat resistance and mitigate whip. Manufactured 100% in-house from cradle-to-grave, these Faxon barrels are fully stress relieved, air-gauge tested, and 11 degree target crowned to ensure superior accuracy.

Each Faxon GUNNER barrel goes through a battery of tests at each manufacturing operation until finished in Nitride and final inspected. All barrels are individually checked for headspace by precision custom hardened gauges.

Was expecting more.

We purchased this barrel for a suppressed SBR. We were trying to keep the weight down so we went this slim profile barrel after hearing what great quality they were. We tried a dozen different types of ammo from 55gr surplus fodder to Black Hills 77gr OTM. Nothing we tried shoots what I would consider acceptable groups. 2-3" at 36 yards was about the best any of them would do. Even switched from an Odin Works can to an OSS Helix and nothing changed. Very disappointing. Going to request a return on this.

Overgassed

I like the barrel profile. Its reasonably accurate. I don't like the fact that it ejects at 1 o'clock shooting XM193. It shoots around 2 o'clock with lower powered ammo and an H3 buffer. I don't want to put a $100 gas block on a $150 barrel to make it work. I'm pretty disappointed. I've got a few Faxon parts, and I like them, but they really dropped the ball on this barrel. They should state that this barrel is for 3 Gun. It is purposefully overgassed so you can use an adjustable gas block, lightweight BCG, etc. to tune the rifle to run a super light load with low moving mass.
