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.

Good looking

Very good looking barrel, but is not dimpled for gas block, which would have been nice.

Amazing Accuracy!

To start this wouldve been a 5 star, but I think the barrel is a little short of the 7.5 length which caused the base of my muzzle device to sit just inside a 7 handguard. This meant I had to get a handguard with a bigger inside diameter so my suppressor would drop inside and lock on. Just keep in mind if using a suppressor. Accuracy wise, this barrel really impressed with most ammo I fed it. I couldnt believe such a stubby little barrel would throw five consecutive rounds of 150 grain Hornady SP in a 3 circle at 100 yards, but it did! That was with a 2MOA red dot optic. I imagine if you put more pinpoint glass on it you could possibly tighten it up more. Additionally Ive had zero cycling issues as well. This barrel even cycled heavier subsonics without a suppressor. I highly recommend it for a CQB hammer thats fully capable of long shots in a pinch.
