Faxon Ar10 Bbl 6.5 Creedmoor 18" 1:8 5r Big Gunner Blk

The Faxon AR-10 barrel in 6.5 Creedmoor with an 18-inch tube and 1:8 twist rate brings match-grade performance to your modern sporting rifle at a price that doesn't require a second mortgage. Faxon manufactures this barrel in-house from 416-R stainless steel bar-stock and applies their proven 5R rifling profile—a hybrid design that spaces lands opposite the grooves with reduced angles to minimize bullet jacket deformation, boost velocity, and make cleaning faster and easier. It's the kind of attention to detail you'd expect from a barrel maker, not a parts bin assembler.

The bore and exterior get salt bath Nitride treatment, which hardens the steel, extends barrel life, and provides genuine corrosion resistance without the theatrical marketing. The extension wears a Nickel Teflon coating that cuts friction, resists rust, and tightens the fit between extension and receiver—measurable improvements that add up to tighter groups and fewer surprises when you dial in at distance. This is a no-nonsense barrel built for hunters and shooters who want precision without paying premium prices for premium results.

The 6.5 Creedmoor cartridge and 1:8 twist are a proven match for factory and hand-loaded ammunition in this caliber. The 18-inch barrel length keeps things handheld without sacrificing the velocity this intermediate-range round is known for. Whether you're ringing steel on the range, hunting across open country, or working up loads in your reloading room, the Faxon Big Gunner delivers the consistency that separates groups from flyers.

Frequently Asked Questions

What AR-10 rifles will this barrel fit?

This barrel is designed for AR-10 platform rifles. The rifle-length gas system with 1.1-inch journal and standard AR-10 threading make it compatible with most AR-10 builds, but always verify your specific receiver and handguard clearance before purchasing.

Is 6.5 Creedmoor a good hunting and long-range cartridge?

6.5 Creedmoor is a popular choice for mid to long-range hunting and competitive shooting. It offers excellent ballistics, manageable recoil, and wide ammunition availability. The 1:8 twist in this barrel is optimized to stabilize the bullet weights and designs commonly used in the cartridge.

What's the difference between 5R rifling and standard rifling?

5R rifling has lands opposite the grooves with reduced angles compared to traditional designs. This geometry reduces deformation of the bullet jacket during the rifling process, which can improve velocity consistency and make barrel cleaning easier. It's a feature often found in match-grade and precision barrels.

Will this barrel need any finishing or break-in?

The barrel arrives ready to use. Normal break-in practices for new barrels—such as cleaning between shots during initial firing—are recommended to establish a stable copper fouling layer, as with any new precision barrel.
