FAXON FIREARMS - 300 AAC Blackout 10.5" 1-8 Twist Gunner Contour BBL QPQ

Great barrel. Faxon is all I use. If you don’t have a Faxon barrel you need to try one I have a 6.5 and 2 300 blk Faxon barrels

I picked this up to replace a 10" BO barrel that I felt was a little too long for the backpack SBR that I wanted for a truck gun. Excellent fit and finish. With a 7 inch hand guard it is the perfect length for my Dead Air Sandman silencer. Topped off with the Law Tactical Folder it fits perfectly in my 5.11 backpack with suppressor removed. Shooting 190 SubX reloads it is supper quiet and more than accurate enough to work in that CQB to 100 yard range I was after. Faxxon makes great barrels at a very reasonable price. I will do business with them again...and again.A+

I am a big fan of the 300 AAC cartridge and have carried one for deer season for 4 out 6 seasons. Im a backpack hunter so weight matters a lot. My current build needed to be replaced due to an operator error incident. I was sad to part ways with my first upper build, it was a very accurate rifle with MOA accuracy at 200 yards. My first time out sighting in the new build, shots 9 and 10 at 100 yards were touching. Now I have an AR build that weighs under 6 lbs with optic, thats some weight off my shoulders. Being the last person I know who breaks in barrels, first shot cleaning took 3 patches. That nitride coating works! Time will tell how the coating holds up. But my sense is that the barrel bore has been properly lapped and chambered, given results on paper so far. The barrels gas porting cycles both supers and subs perfectly without a buffer weight or spring change. I use a YHM non-adjustable clamp on block and a standard bolt carrier. I have the Brownells Nickel boron lightweight carrier for hunting season use , Im confident that the lightweight carrier will cycle well, but will report back if it doesnt. If you handload subs, CFE BLK and H-4198 cycle well, now to test for accuracy. My pet load for supers from the old barrel gave the accuracy mentioned above. Hornady 110 grain VMax over 18.3 grains lil gun. Now to go find those deer...

Faxon makes great barrels. My problem is with the description of this barrel (15A38P10NGQ) 10.5" GUNNER, 300BLK. Description states 5R rifling. Come to find out, the Faxon Match Series barrels have the 5R rifling not this model of barrel. Brownells made a mistake in the description and I bought it thinking it was a 5R barrel. It is still a great barrel, just not 5R rifled like the description stated. I will be returning this barrel for a true 5R Faxon Match Series barrel.

Used this in an AR pistol build, loving the results! Nickel size groups at 50yards, with merely a Romeo5 red dot. Can easily reach 100yard kill zone with Hornady 135grain supersonic. No issues with ejection with all 3 pistol, H1, and H2 buffers(keeping H2 buffer in for best ejection pattern). Never had any headspace issues with either Faxon barrel builds yet. Simply can't go wrong buying a Faxon barrel!
