How a Savage® 110 Barrel Swap Works

Savage® 110 rifles were designed for barrel swaps. The barrel threads into the action and a barrel nut locks it in place, so headspace is set at installation instead of machined into a shoulder. Thread the barrel in until a GO gauge just closes the bolt, tighten the included Savage®-style barrel nut against the receiver with a Savage barrel nut wrench, and confirm with a NO-GO gauge.

This barrel fits Savage® 110 and other Savage® small shank actions with a 1.0625-20 tenon. It does not fit large shank Savage® actions (including the 110 PCS), Remington 700®-pattern actions, or the Faxon FX7.

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 12″

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, 1.0625-20 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.

Savage® 110 12″ Medium Sporter 8.6 BLK FAQs

Will it fit my Savage®?

It fits Savage® 110 and other Savage® small shank actions with a 1.0625-20 tenon. It does not fit large shank actions, including the 110 PCS, and it does not fit Remington 700®-pattern actions or the Faxon FX7.

How do I install it?

Thread the barrel in until a GO gauge just closes the bolt, tighten the included barrel nut against the receiver with a Savage barrel nut wrench, and confirm with a NO-GO gauge before firing.

What comes in the box?

The barrel and Savage®-style 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.
