Great product by Build a bear, 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!

Faxon 7.5" 300 Blackout by Vic, January 12, 2024

should be standard by Elliott Jones, Verified Owner, 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.

The best 300 Blackout barrel by Paul, Verified Owner, February 8, 2024
The 7.5" with 1:5 twist is the best 300 blackout barrel. I don't think anything less than 7.5" is decent enough, even though someone might find it attractive. The 7.5" has excellent ballistics of a longer barrel while being short enough to stay packa...

Product Info for Faxon Firearms Match 300 BLK Barrel

A faster 1:5 Twist Rate combined with the Lightweight Faxon Gunner Profile.image

The 300 Blackout cartridge yields increased performance in shorter barrels and effective subsonic performance. By speeding up the twist rate to 1:5 from common 300 BLK rates of 1:7 and 1:8, these Faxon Match Series Gunner Barrels increase projectile stabilization and energy on target.

The Gunner profile is a blend of two of the best performing profiles of all time, GOVT/SOCOM and Pencil. Faxon's Gunner profile combines the durability of the GOVT/SOCOM profile with the weight savings and maneuverability of the Pencil profile. The Gunner profile brings the balance of the rifle back towards the shooter's body, limiting fatigue, and allowing for shooting, training, or hunting all day long.

Faxon Firearms barrels are the pinnacle of value. Manufactured in-house in Greater Cincinnati, Ohio, Faxon barrels are fully stress relieved, air-gauge tested, and 11-degree target crowned to ensure superior accuracy. Quality is imbued into Faxon Firearms barrels from the beginning of the manufacturing process. Faxon Match Series Barrels are made of 416-R Stainless Steel, given 5R rifling, and a NP3 (Nickel Teflon) barrel extension. Faxon barrels are Magnetic Particle Inspected (MPI) in-house do assure the greatest quality for a lifetime of service.

Each barrel goes through a battery of tests at each operation until finished in Nitride and final inspected. All barrels are individually checked for headspace with precision, custom-hardened PTG gauges.
