FAQs

Is this FX7 barreled action truly ready to build from?

Yes. This is a complete barreled action with the barrel installed and the bolt included. Each unit is headspaced and function-checked at Faxon Firearms in Cincinnati, Ohio so you can drop it into a compatible stock or chassis and finish your build with a trigger, bottom metal/magazine system, and optic.

What makes the Faxon FX7 a great 8.6 Blackout bolt action platform?

The FX7 combines a strong 6-lug bolt design, a smooth 70-degree bolt lift, and a suppressor-ready 12" 8.6 BLK barrel with 5R rifling and a fast 1:3 twist. It’s engineered for reliable cycling, repeatable accuracy, and consistent performance with the heavy subsonic bullets many shooters choose for 8.6 Blackout.

What stocks, chassis, and triggers are compatible?

The FX7 barreled action is compatible with Remington® 700 short-action stocks and chassis systems and Remington® 700 pattern triggers. Some stocks may require minor inletting to accommodate the trigger hanger.

Is this setup suppressor-ready?

Yes. The barrel features M18x1.5 RH muzzle threads with a tapered shoulder, and a taper adapter is included. This helps support secure alignment and repeatable mounting—ideal for compact suppressed 8.6 Blackout bolt rifle builds.

Why does this barrel use 5R rifling, and what’s the benefit?

Faxon’s 5R button rifling (honed and lapped) is designed to reduce jacket deformation, improve consistency, and make cleaning easier—supporting long-term accuracy and dependable field performance.

Will any 8.6 Blackout ammo work in this barreled action?

Not always. We have seen inconsistencies across commercially available 8.6 Blackout ammunition. Ammunition that does not match the cartridge print cannot be guaranteed to function properly. Additionally, ammo made for semi-auto rifles may have harder primers and could cause light primer strikes in some bolt-action applications.

Where is the Faxon FX7 barreled action made?

Faxon Firearms is a family-owned manufacturer, and FX7 barreled actions are produced and assembled in the USA with in-house quality control, including headspace verification before shipment.
