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.

Poor accuracy

Built an AR around this barrel. I wanted a lightweight, high accuracy setup for ease of carry and use. Wasn't looking for sub MOA accuracy, 1.5 to 2 would have been great. From a bench rest this rifle never shot better than 4 MOA with several different decent quality varieties of ammo. I will be returning it for a refund to get a quality barrel. I expected much better from a very expensive barrel.

Poor Accuracy

The accuracy of this barrel is the worst I have seen in building numerous ar15 rifles over 20 years. I have had barrels cost half as much beat this. It would not group with any of three bullet styles and weights tested, including known accuracy loads that shoot well in three other rifles. Groups ranged from 2 and 1/2 inches to over 4 and 1/2 inches shooting 3 types of Sierra bullets, not cheap FMJ stuff. These loads all shoot 3/4 to 1 and 1/2 inches in all rifles I have shot them in. I will not address any positive features of the barrel because it is so inaccurate as to be useless. Every low grade non- free floated generic ar-15 I have ever tested shot better than this. I will be contacting the manufacturer to see if they stand behind their product.
