How a RemAge® Barrel Works

A traditional Remington 700® barrel is chambered and shouldered on a lathe to fit one specific action. A RemAge®-style barrel replaces the machined shoulder with a barrel nut, the way Savage® barrels have always worked. Thread the barrel into the action until a GO gauge just closes the bolt, snug the nut against the receiver to lock it there, and check with a NO-GO gauge. The included RemAge® barrel nut is tightened with a standard AR-15 armorer’s (castle nut) wrench.

RemAge® barrels fit factory Remington 700® short actions and similar 700-pattern short actions, and Faxon RemAge® barrels made since December 2023 also fit the Faxon FX7. Because the nut sets headspace, the same barrel works across actions whose bolt-face depth varies.

8.6 Blackout, 1:3 Twist

8.6 Blackout fires heavy .338 bullets from a short-action case and was designed around suppressed use. The original 1:3 twist spins heavy subsonic bullets fast enough to expand at subsonic speed. Use ammunition loaded for a 1:3 twist.

Learn more in Faxon’s 8.6 Blackout guide. The M18x1.5 muzzle has a tapered shoulder, and the taper adapter in the box lets you run standard M18x1.5 muzzle devices and suppressor adapters. For suppressors, pick a .36 caliber can such as the HARMONIX® ION .36.

The Medium Sporter Profile at 16″

The Medium Sporter is a classic sporter contour with more steel than a light hunting barrel. It balances weight and stiffness for rifles you carry and still want to shoot well from a bench, and it is a natural fit for short suppressed builds.

Ammunition note: 8.6 BLK ammunition on the market varies. Use ammunition loaded for a 1:3 twist and built to the cartridge print. Loads made for semi-auto rifles can have hard primers that cause light strikes in bolt actions.

How It’s Made

1. Drill and ream: 416-R stainless bar gun-drilled and reamed
2. Hone: Bore honed to a fine finish before rifling
3. Button rifle: 5R button rifled, 1:3 twist
4. Air gauge: Bore air gauged
5. Stress relieve: Stress relieved after rifling
6. Profile and thread: Medium Sporter profile turned, 1.0625-16 UNEF tenon and M18x1.5 muzzle threads cut, target crown
7. Chamber: 8.6 Blackout chamber cut
8. Lap: Bore lapped after chambering
9. MPI and nitride: 100% wet magnetic particle inspected, then salt-bath QPQ nitrided inside and out
10. Engrave and inspect: Laser-engraved with the cartridge and twist, then final inspected

Salt-bath QPQ nitride is a diffusion treatment, not a plating. It hardens the bore and exterior and adds corrosion resistance while adding virtually nothing to the dimensions, a few ten-thousandths of an inch, roughly a tenth the width of a human hair. It needs little to no break-in.

RemAge® 16″ Medium Sporter 8.6 BLK FAQs

What is a RemAge® barrel?

A Remington 700®-pattern barrel that uses a barrel nut to set headspace instead of a machined shoulder. You thread it in to a GO gauge and lock the nut, so you can install it without a lathe.

What actions does it fit?

Factory Remington 700® short actions and similar 700-pattern short actions, plus the Faxon FX7 (on RemAge® barrels made since December 2023).

What tools do I need?

A barrel vise, an action wrench for your receiver, an AR-15 armorer’s (castle nut) wrench for the RemAge® nut, and GO/NO-GO headspace gauges for the cartridge.

What comes in the box?

The barrel and RemAge® barrel nut, thread protector and taper adapter.

Why 416-R stainless and 5R rifling?

416-R machines cleanly and holds a consistent bore. 5R rifling uses five lands with sloped sides instead of sharp corners, which deforms the bullet less and fouls less. Faxon hones the bore before rifling and laps it after chambering for a smooth, consistent finish.

Does a nitrided barrel need break-in?

Little to no break-in. Salt-bath QPQ nitride hardens the bore and resists corrosion and fouling while adding virtually nothing to its dimensions.

Can I run a suppressor?

Yes. The muzzle is threaded M18x1.5 with a tapered shoulder; use the included taper adapter with standard M18x1.5 devices and adapters, and a .36 caliber or larger suppressor.

What ammunition should I use?

Ammunition loaded for a 1:3 twist and built to the 8.6 BLK cartridge print. 8.6 BLK ammunition on the market varies, and loads with hard semi-auto primers can cause light strikes in a bolt action.

Where is it made?

In Greater Cincinnati, Ohio, and it is covered by the Faxon Lifetime Guarantee.
