Most Helpful Positive Review Faxon 7.5" 300 Blackout
I always recommend Faxon barrels for 300 blk mainly because the gas port is a perfect diameter. As far as the shipping, Im furious it came losely packed inside of a thin shipping bag with zero bubble wrap, it is a 7.5" barrel that was put in a 20" x 20" plastic bag so i'm 100% sure its been dropped and banged around judging by the scuffs on the barrel itself.

should be standard

by Elliott Jones, Verified Owner from AL, United States Written on February 16, 2025
Swapped out a 1:8 barrel for this. Transformed my gun. Very accurate. Loves subs and supers! I used a small zip tie to align the gas port. Pushed the zip tie thru the holes for alignment.
Pros:
  • Price
  • performance

  • Not Dimpled

Great product

by BuildAbear, from SC, United States Written on December 14, 2024
Best option I've found for a supressed SBR set up. The 1:5 twist is perfect for dedicated subsonic applications and with proper match ammo it groups quite nicely at ranges built for this purpose. Very happy with this purchase!
Pros:
  • twist rate
Cons:
  • No dimple
Best Used for:
  • Dedicated subsonic
Would recommend: Yes

The best you can buy

by The Gripper, Verified Owner from TN, United States Written on November 8, 2024
Great barrel but it’s best to get a Faxon gas block and tube from faxon when you buy this barrel because faxon barrels have e pretty large gas whole that exactly matches their gas block’s whole other wise you will have to line up the gas whole perfectly if you use a non-faxon gas block or risk a gas leak or possibly not getting enough gas through your gas tube which might cause a failure to cycle. It’s ok to use a non-faxon gas block but your alignment will have to be precise so save yourself the trouble and just pair faxon barrels with faxon gas blocks and gas tubes.

Exactly what I need

by The Gripper, Verified Owner from TN, United States Written on November 1, 2024
So far so good, it’s well made and it has great finish. The gas whole on the barrel is a little larger than on most barrels so it’s a good idea to also get a Faxon gas block which perfectly fits the barrel whole but any gas block will still work.
