It's a shame I can't post images. I'm getting groups of less than an inch at 100 yards with standard ammunition. I have a few faxon barrels all very accurate. With match ammo at 200 yards and not a lick of wind I easily got under 2 inch groups. Fit and finish were also excellent. Nice work gents!

I built my first 300AAC with the 16" Faxon gunner profile barrel. It did extremely well with 110V-Max. I consistently had 5 shot groups at 100 yards smaller than a quarter. It was still sub MOA on 3 shot groups with 150gr hunting SPBT rounds. I'm only using Faxon from now on.

The shipping was fast. The price was great. The quality of the Faxon Firearms barrel is amazing! I am very happy with Optics Planet and Faxon Firearms. I would absolutely recommend this barrel to anyone looking to build a 300 BLK pistol or SBR.

I've brought this barrel for my 2nd build (.300 blackout pistol). I'am still in the process of building this pistol. There isn't many companies selling this barrel in the 9" length. I love the nickel plated extension only somewhat con is I had to thermo-fit into the receiver. At the same is a good thing, tighter tolerance for accuracy! Love the profile to help shed some weight. I'am definitely considering purchasing a 16" faxon gunner to replace my inexpensive bbl in my 1st build!

Ok if you don't know anything about .300 blackout maybe you shouldn't even be building one until you do some research . . First off , the gas port most likely isn't too small. You will rarely find a 300 bo that will reliable cycle subsonic ammunition WITHOUT a suppressor or at least a good krink style break to create back pressure as the gas port size is tuned to run supers and run subsonic with a suppressor . Next if you don't have a suppressor, you don't need an adjustable gas block on .300 bo. Probably still wouldn't need an adjustable gas block even with a suppressor cause the barrels gas port is tuned to the correct size for optimal performance. Can't see someone writing a bad review over their own lack of knowledge.
