Description
The 8.6 Blackout is one of the more interesting cartridges to come along in years, and Faxon jumped on it early by partnering with Q during development. This 12" barrel is built specifically for that round, machined from 416-R stainless steel at Faxon's facility in the greater Cincinnati area. The short length makes it a natural fit for a compact, suppressed bolt gun, and the salt bath nitride finish inside and out keeps corrosion and fouling in check while stretching out barrel life.
The headline here is that 1:3 twist rate. It sounds extreme because it is, and that is the whole point. 8.6 Blackout runs long, heavy subsonic projectiles, and it takes a fast twist like this to spin them up properly. That aggressive rotation is what drives the terminal performance the cartridge is known for, especially when you are running suppressed and subsonic. The barrel wears an M18x1.5 muzzle thread with a tapered shoulder, so mounting a can or thread protector is straightforward.
What Sets This Faxon 8.6 Blackout Barrel Apart
Faxon does not cut corners on the process. Each barrel is fully stress relieved, air-gauge tested, Magnetic Particle Inspected, and finished with an 11-degree target crown to protect the rifling and keep groups honest. It is the same treatment Faxon puts across its precision line, and it shows in the fit and finish that builders consistently point out.
Fitting the Faxon Savage 110 8.6 BLK Barrel to Your Action
This one is designed for the Savage 110 and Savage Small Shank pattern using the standard barrel nut system. It is not a true drop-in prefit, so plan on headspacing it with go/no-go gauges and torquing the nut correctly, which is a job best handled by someone comfortable behind a barrel vise. Worth knowing up front: it is not compatible with the Savage 110 PCS large shank or with Faxon's FX7 actions. Get it on the right receiver and you have a compact 8.6 BLK build that punches well above its size. It is backed by the Faxon Lifetime Guarantee against manufacturing and material defects.

Frequently Asked Questions
What rifle does this Faxon 8.6 Blackout barrel fit?
It is built for the Savage 110 and Savage Small Shank pattern receivers using the standard barrel nut system. It is not compatible with the Savage 110 PCS large shank or with Faxon's FX7 bolt-action receivers. Double-check your action's shank before ordering.
Is the Faxon Savage 110 barrel a true drop-in prefit?
No, it is not a drop-in prefit. You will need to headspace it with go/no-go gauges and torque the barrel nut properly during install. If you are not set up for that, a qualified gunsmith can handle the swap in short order.
Why does the 8.6 Blackout barrel use such a fast 1:3 twist?
8.6 Blackout is designed around long, heavy subsonic bullets, and that aggressive 1:3 twist is what stabilizes them and maximizes rotational energy. That fast spin is a big part of the cartridge's terminal performance, particularly when running suppressed and subsonic. It is a purpose-built spec, not overkill.
Is this barrel suppressor ready?
Yes. The muzzle is threaded M18x1.5 with a tapered shoulder, which is the standard interface for 8.6 BLK cans and adapters. It ships with a thread protector and taper adapter so you are covered whether or not you are mounting a suppressor right away.
