Most Helpful Positive Review .308 16" gunner
I got a .308 16" gunner barrel. Its a fantastic lightweight barrel. I did check headspace and it did not meet march grade headspace. But what I think people fail to realize is that this is supposed to be more of a 7.62 NATO chamber. So its not going to headspace with match grade gauges. It will pass...

Most Helpful Negative Review Headspace failed
Tried two Faxon 308 barrels- both failed headspace check by a gunsmith, using two separate BCG' one FailZero and a Brownells. Contacted Faxon directly- not a positive outcome. They tried to explain that they see this problem with bolts that are .186 vs .188" or vise versa. That it will fail on a ...

headspace issues

by sophia, Verified Owner from CO, United States Written on August 24, 2025
Barrel is out of spec. Tried two Faxon bcgs in it. Both would get locked in the chamber but worked with another 308 barrel. I would not recommend it. It's a dangerous defect that seems to be common.
Would recommend: No

Faxon firearms big gunner

by bree, from FL, United States Written on August 7, 2023
Building a 308 compact hunting rifle. Great quality and it has the longer gas block surface that allows the use of an adjustable RifleSpeed
gas block for my suppressor. Very accurate and I'm pleased with it.

Defective barrel and worse customer service

by Mike, from AZ, United States Written on May 18, 2022
I ordered the 18" version of this barrel. It had terrible accuracy due to a defect in the chamber that scratched every bullet and casing that went into the gun. Contacted Faxon, they agreed to replace the barrel. They never sent a new barrel, they haven't responded to any emails after agreeing to RMA my barrel. Stay away from Faxon.
Pros:
  • Makes a nice paperweight
Cons:
  • No customer service - broken promises
Best Used for:
  • trash at the moment
Would recommend: No

Great Product

by JLewis, Verified Owner from TX, United States Written on February 24, 2022
Bought this as a new build for a truck/hog gun. Arrived with a few scratches (not a deal breaker) but only worth 4 stars for that. Barrel shoots tight and handles well. The only con I would have would be that the gas block area didn’t have indentions for the set screws but again, not a deal breaker.
Would recommend: Yes

Very light weight

by Robert Davis, Verified Owner from WA, United States Written on August 14, 2021
I had a 20 inch barrel on my Maten-308 that weighed 50.4 ounces, great barrel but just too heavy so i bought this Faxon and swapped them out.

Drooped just over a full pound but it feels a full ton lighter.

Havent broke in the barrel yet but it shoots just fine so far.

Getting just over an inch MOA with ball ammo so i expect an easy sub MOA with the good stuff.

Very pleased over-all with bith Faxon and Optics Planet

Nice shooter.

by Eric Evans, Verified Owner from NC, United States Written on June 10, 2021
Shoots nice from bench as I have shot sub MOA groups with it but also does well to shoot offhand. Using Aero Precision Upper and lower receiver and bolt carrier group everything fits nicely together and comes in at 8 and a half pounds with empty magazine. Balance is great. Faxon did a good job of making a great shooting barrel and also keeping it lightweight. i would recommend this to anyone who wants to build a well rounded AR 308 rifle.
Would recommend: Yes

Faxon barrel

by Larry J. Hartwick, from MI, United States Written on February 24, 2021
Great Barrels, shoot great , clean great. I've used a bunch of them, never had a dud. I've used their 223 Wylde , 6.5 Creedmoor and 308 win barrels. All are very capable of sub 1/2 moa with good handloads. Factory decent ammo definitely under 1 moa. You won't shoot that well with a mil spec trigger.
Pros:
  • Shoot great.
Cons:
  • Wish they were a little less $
Best Used for:
  • hunting and target
Would recommend: Yes

So Far So Good/ Go No Go

by Jackal, Verified Owner from TX, United States Written on January 21, 2021
Installation was a breeze. Visual inspection went well. I am running with a nickel boron Aero Precision bcg and everything matched up as hoped. For headspace I used Clymer Precision .308 match go/ no go set and everything went perfectly. I was a little surprised, due to the reviews, of how well it went, but the Clymer Precision's from Brownels, although a little more expensive, fit (or didn't fit) perfectly. No need for field gauge. I'm sure if you go with this barrel and a well known bcg you should be ok. I not only went with Aero Precision because of the brand itself, but also because they were one of the recommendations which can be found on Faxon Firearms webpage. I will update as to accuracy once I get to the range.
Pros:
  • Go/No Go + Weight/ Thickness ratio
Cons:
  • none yet
Best Used for:
  • Plinking/ Hunting - white tail/ Target
Would recommend: Yes

Headspaced just fine with forster guages, had the chamber cut by POF afterward

by Dave, from CA, United States Written on August 8, 2018
bought this barrel on sale and threw it into a lightweight build, headspaced just fine with a cryptic coatings bcg and forster gauges, thought i would have tolerance stacking problems like the other review here, but everything worked first try no problem. got some nice vids of me shooting the rifle. had the chamber cut by patriot ordnance factory by purchasing their e-squared service, the necks of the cases have little black puffs from being pushed out w this feature, cheap effective barrel that was putting moa groupings with match ammo and a rest in windy conditions, no real need for a finer quality barrel unless you want to get scientifically accurate with all the rest of your parts or lock your rifle in a vise for shooting and really get serious, you pay exorbitantly for diminishing returns at that level, this barrel does it all for much less and to nearly the same degree as barrels costing 3x
Pros:
  • value and quality
Cons:
  • None
Best Used for:
  • range toy, plinking
Would recommend: Yes
