Frequently Asked Questions
What ammo works best with 1:8 twist?
1:8 stabilizes a wide range of 300 BLK bullets—from light supersonic to heavy subsonic—for versatile use, suppressed or unsuppressed.
Is the barrel suitable for suppressed builds?
Yes—its pistol-length gas and compact 9" format are popular for suppressed 300 BLK platforms.
Why 5R rifling?
5R places lands opposite grooves and softens sharp angles to reduce jacket deformation, improving accuracy and cleaning.

Faxon 9 inch Gunner Barrell
I recently purchased this barrell and cannot be any happier. This thing is above expectations. I will definitely be using the barrells on ALL my rifles from here on out.

Great Upgrade
I got this to upgrade from a PSA barrel (which was okay) but this is a far more accurate barrel. I recommend it.

Awesome barrel!
Surprise surprise, yet another fantastic product from Faxon! Long time fan of Faxon barrels, this one has not disappointed. Run on my ar15 pistol for 300blk with my Omega300 can and its a beautiful match up. Haven't measured but I'm hitting very tight groups at anything inside 50yds. Not sure how it would perform out beyond that range but that's not my build intention so I'm very happy with this. Put a couple hundred to a thousand rounds of varying kinds of factory ammos, no issues with any of them. Truly pleased with my purchase!

9" barrel
i was surprised when i got the barrel that there was a imperfection in the finish on the barrel and the bore hadnt been cleaned prior to shipping. i bought this barrel since my last barrel was a flawless example and offered all the features i wanted. I figured the match barrel would be more of the same. after cleaning the bore it is just waht i would expect but the imperfection in the finish is something i would expect to be caught before it was shipped. Maybe im just being too critical but i expected more based on my past purchase from Faxon.
