Faxon RemAge® Style — 12" Medium Profile 8.6 Blackout Bolt Action Barrel (1:3 Twist)

416-R stainless • Button rifled • QPQ nitride inside & out • M18x1.5 tapered muzzle • RemAge® barrel nut included

The Faxon RemAge® 12" 8.6 Blackout barrel is built for compact, suppressed bolt-action setups that demand modern 8.6 BLK performance. Developed in partnership with Q, the aggressive 1:3 twist rate is engineered to stabilize heavy 8.6 projectiles and harness rotational energy for consistent subsonic and supersonic performance.

Starting with 416-R stainless steel, each barrel is fully stress relieved, air-gauge tested, magnetic particle inspected (MPI), and finished with a durable salt bath nitride (QPQ) treatment inside and out. A crisp 11° target crown supports repeatable accuracy.

Important Notes

FX7 Compatibility: Barrels produced before job number 8946 are compatible only with factory Remington® 700 actions and similar. As of 1/8/24, barrels are compatible with both factory R700 and Faxon FX7 actions and similar.

Installation: The RemAge® barrel nut requires a standard AR-15 castle nut wrench to torque into spec.

Frequently Asked Questions

Why does 8.6 BLK use a 1:3 twist?
8.6 Blackout is designed around long, heavy projectiles. The fast 1:3 twist is intended to stabilize these bullets and maximize rotational energy for consistent performance.
Is this barrel suppressor-ready?
Yes. The barrel uses M18x1.5 muzzle threads with a tapered shoulder. A taper adapter is included for proper mounting.
Can I use semi-auto 8.6 ammo in a bolt gun?
Some semi-auto loads use harder primers. In bolt-action rifles this can increase the chance of light primer strikes. Confirm primer hardness and function before relying on any ammunition.
What’s included with the barrel?
This RemAge® barrel ships with a barrel nut, taper adapter, and thread protector.

    As a manufacturer in the 8.6 Blackout sphere, we’ve conducted endless amounts of testing and development and can confidently say that the new Faxon 1:3t is the biggest contributing factor to the consistent accuracy we’re seeing w solid copper expanding projectiles. Excellent job Faxon!

    12” 8.6 Blk remake barrel

    Posted by Brian Blanchard on Jun 7th 2023

    I purchased this to replace a 308 barrel in a Remington 700CP pistol. The barrel is amazingly accurate. The first 9 shots (3 groups of 3 shots) as I sighted in the rifle result in three sub MOA groups at 100 yards using Gorilla 210gr TSX ammo. I was not expecting this type of performance from such a short barrel. I highly recommend the barrel.
