The Universal Arca Rail by Buff Stuff delivers a solid, lightweight chassis interface for hunters and precision shooters without replacing their factory stock.

The Buff Stuff 3.5" Universal Arca Rail is built for hunters and precision shooters who demand a solid, lightweight chassis interface without replacing their factory stock. Designed to fit a wide range of popular rifle platforms — including Savage, Ruger, and Howa — these universal arca rails bring professional-grade functionality to your existing setup at an accessible price point.

Universal Arca Rail — Fit, Finish & Compatibility

The Browning X-Bolt Stalker shown in the photo features the R11 ARCA plate. It also works great on Varitech stocks with the additional hardware. That hardware includes custom nuts and washers that locate within the Varitech stock for a clean and simple install.

The Savage Axis 2 shown in the photo features the R20 ARCA plate. The Savage Axis XP Predator Camo shown in the photo features the R15 ARCA plate. Not sure which radius fits your stock? Use the radius checker tool linked above before ordering.

Each rail is precision-machined from aircraft-grade CNC Aluminum — specifically 6061-T6 billet — keeping weight low without sacrificing rigidity. The fluted design is hot Cerakoted to match stainless/nickel or blued/black barrels, so it integrates seamlessly with your rifle's existing finish.

Stainless steel hardware is included with every order. A rear back stop is designed directly into the rail, eliminating the need for additional positioning hardware during setup. Installation requires custom fitting, so basic tools and mechanical confidence are recommended.

Whether you're running Arca Rails on a dedicated hunting build or a field precision rig, Buff Stuff delivers the quality and fitment accuracy that makes the difference at the range or in the field. These rails are a popular upgrade for Savage, Ruger, and Howa platform owners looking to add bipod or tripod compatibility without a full chassis swap.
