300 BLACKOUT GUNNER PROFILE RIFLE BARRELS FOR AR-15

300 BLACKOUT GUNNER PROFILE RIFLE BARRELS FOR AR-15 Reviews & Ratings

Faxon’s .300 AAC Blackout Gunner Barrels are machined from hardened 4150 Chrome moly in a unique contour that balances rigidity - for excellent accuracy - with light weight for maneuverability. From the muzzle back to the gas block .300 AAC Blackout Gunner Barrels match Faxon’s skinny "Pencil" profile to keep weight down and preserve ease of handling. There’s more metal from the gas block back to the barrel extension to provide rigidity and combat distortion due to heat buildup during long shooting sessions.

Terrible
I had this barrel for a year and tried multiple different ammunition weights by multiple manufacturers and every round would keyhole. I would get the occasional round that flew straight but they were few and far between. Fortunately Brownells is top notch and is accepting my return a year later. Im going with the 10.5 this time, I just dont think the 7.5 barrel with a 1-8 twist spins the round quick enough to stabilize it. Or maybe I got a bad barrel. I tried everything before giving up on this barrel.
