FAXON FX7 MATTE DLC BOLT ACTION RECEIVER - .308 BOLT FACE
FaxonDescription
What Is the Faxon FX7 Bolt Action Receiver?
The Faxon FX7 is a precision bolt action receiver manufactured by Faxon Firearms in Cincinnati, Ohio. It is built on the Remington® 700 short-action footprint — the most widely supported standard in custom rifle building — which means it accepts Remington 700 pattern triggers, stocks, chassis systems (KRG, MDT, Magpul, XLR, Manners, McMillan), and scope bases without modification.
The receiver body is machined from 416 stainless steel and finished with ArmorLube™ Matte DLC (Diamond-Like Carbon) — the mil-spec coating designated MIL-PRF-32711. ArmorLube™ is a PVD-applied coating that increases surface hardness, reduces friction, and improves corrosion resistance while providing a satin, low-glare finish ideal for field and tactical use. The bolt is machined from 4340 carbon steel with the same ArmorLube™ treatment and features Faxon’s signature flame fluting — a design element borrowed from their industry-leading barrel line.
Unlike legacy Remington 700 actions that use a two-lug bolt requiring a 90-degree throw, the FX7 uses a six-lug configuration arranged in two rings of three lugs. This allows a shorter 70-degree bolt lift, providing faster cycling and greater clearance under low-mounted optics. The FX7 also includes an integrated 20-MOA Picatinny rail and an integrated recoil lug, eliminating two components that are typically purchased and installed separately on other platforms.

Engineering Highlights
ArmorLube™ Matte DLC (MIL-PRF-32711)
Both the receiver body and bolt assembly are coated with ArmorLube™, a Diamond-Like Carbon (DLC) coating applied via physical vapor deposition (PVD). ArmorLube™ is the mil-spec coating designated MIL-PRF-32711 — the same specification used by DEVCON for military and defense applications. It achieves surface hardness significantly exceeding traditional nitride or Cerakote finishes while providing a satin, low-glare surface that reduces visual signature in the field. Unlike coatings that sit on top of the substrate, DLC bonds at the molecular level, meaning it will not chip, flake, or peel under normal use.
6-Lug Bolt with 70-Degree Throw
The FX7 bolt uses six lugs arranged in two rings of three, which distributes locking force more evenly across the bolt face than a traditional two-lug design. The 70-degree bolt throw — compared to the 90-degree lift on a standard Remington 700 — means the bolt handle travels a shorter arc, providing faster cycling and greater clearance under low-mounted optics. The shorter lift also reduces the chance of knuckle interference with large objective scopes.
M16-Style Extractor & Plunger Ejector
The FX7 uses an M16-style extractor machined from S7 tool steel rather than the traditional Sako-style or Remington clip extractor. S7 tool steel is a shock-resistant grade chosen for its ability to withstand repeated impact loading without fracture. The plunger-style ejector uses a 12L14 steel body with a coil spring, delivering consistent, positive ejection regardless of cycling speed.
Premium Internal Components
Every component in the FX7 is purpose-selected for its role. The firing pin is 17-4 PH stainless steel heat-treated to H900 condition for optimal hardness and fatigue resistance. The cocking piece and bolt stop are 4340 carbon steel with flash nitride for wear resistance. The trigger hanger is 416 stainless steel with nitride coating, and the bolt shroud is 416 stainless steel with flash nitride. Firing pin and extractor springs are sourced from W.B. Jones, a specialist spring manufacturer.
Flame-Fluted Bolt
The bolt body features Faxon’s signature flame fluting — a pattern inspired by their barrel line that is both functional and distinctive. Flame fluting reduces bolt weight, increases surface area for improved debris clearance, and adds a visual design element unique to the FX7 platform.

FX7 Barrel Options & Tenon Specifications
The FX7 accepts Faxon FX7 Prefit barrels, which are headspaced at the factory and thread directly onto the receiver — no gunsmith required. It is also compatible with Faxon RemAge-style barrels. For those working with a gunsmith on a custom barrel, Faxon offers profiled barrel blanks. The tenon drawing below shows the barrel-to-receiver interface dimensions.
Faxon also offers the FX7 Action Wrench for barrel installation and removal.

Frequently Asked Questions
What is the Faxon FX7 bolt action receiver?
The Faxon FX7 is a precision bolt action receiver machined from 416 stainless steel with an ArmorLube™ Matte DLC (Diamond-Like Carbon) finish. It uses a 6-lug bolt design with a 70-degree throw, includes an integrated 20-MOA Picatinny rail and integrated recoil lug, and is built on the Remington 700 short-action footprint for broad aftermarket compatibility. The .308 bolt face version supports .308 Winchester, 6.5 Creedmoor, 6mm Creedmoor, 6GT, and 8.6 BLK calibers.
What is ArmorLube™ DLC?
ArmorLube™ is a Diamond-Like Carbon (DLC) coating designated MIL-PRF-32711 — the mil-spec used by DEVCON for military and defense applications. It is applied via physical vapor deposition (PVD) and provides exceptional surface hardness, low friction, and corrosion resistance. The Matte variant produces a satin, low-glare finish ideal for field, hunting, and tactical use.
Is the FX7 compatible with Remington 700 stocks, triggers, and chassis?
Yes. The FX7 uses the Remington 700 short-action footprint and is compatible with Remington 700 pattern triggers (TriggerTech, Timney, Bix'n Andy, Jewel, etc.), chassis systems (KRG, MDT, Magpul, XLR), and stocks (Manners, McMillan, Bell & Carlson). Some stocks may require minor inletting to accommodate the FX7 trigger hanger.
What is the difference between the Matte DLC and Polished DLC versions?
Both versions use Diamond-Like Carbon (DLC) coating applied via PVD with the same hardness, corrosion resistance, and lubricity benefits. The Matte DLC (this model, FX700SA-308-01, $899) uses ArmorLube™ (MIL-PRF-32711) for a satin, low-glare finish. The Polished DLC (FX700SA-308-02, $999) has a high-gloss, mirror-like finish. The choice is primarily aesthetic and functional — matte for reduced visual signature, polished for a showcase appearance.
What calibers does the .308 bolt face support?
The .308 bolt face (.470" diameter) supports .308 Winchester, 6.5 Creedmoor, 6mm Creedmoor, 6GT (6mm Dasher variant), and 8.6 BLK. These all share the same bolt face diameter. Faxon offers FX7 Prefit barrels in each of these calibers, ranging from 12" (8.6 BLK) to 26" (6GT, 6mm Creedmoor) in Gunner, Medium Sporter, and M24 profiles.
Why does the FX7 use a 6-lug bolt instead of 2-lug?
The 6-lug design distributes locking force more evenly across the bolt face than a 2-lug configuration, promoting more consistent lockup. It also allows a shorter 70-degree bolt throw (vs. 90 degrees on a 2-lug action), which means faster cycling and more clearance under low-mounted scopes. The trade-off is slightly more complex manufacturing, which Faxon addresses with precision CNC machining from bar stock.
Do I need a gunsmith to install an FX7 Prefit barrel?
No. Faxon FX7 Prefit barrels are headspaced at the factory and thread directly onto the receiver — no lathe work or gunsmith is required. The FX7 is also compatible with Faxon RemAge-style barrels. Faxon offers a barrel installation service ($20) if you prefer to have it done for you, and sells an FX7 Action Wrench for DIY installation. For those wanting a custom barrel from a gunsmith, Faxon offers profiled barrel blanks. The tenon drawing on this page provides the barrel-to-receiver interface dimensions.
What magazines does the FX7 accept?
The FX7 accepts AICS and AW pattern magazines, the standard for modern precision and tactical bolt action rifles. Compatible options include Magpul AICS PMAGs, MDT metal AICS magazines, and Accurate-Mag AICS magazines, among others. Magazine compatibility may also depend on your chassis system.
Where is the Faxon FX7 made?
The FX7 is designed and manufactured by Faxon Firearms at their facility in Cincinnati, Ohio, USA. Faxon is an ISO 9001:2015 certified manufacturer. The FX7 is covered by Faxon’s Lifetime Guarantee, which covers manufacturing and material defects to the original purchaser.
