Aero Precision Chassis Spigot Picatinny/Arca Black

The Aero Precision Chassis Spigot Picatinny/Arca is a precision mounting interface designed for shooters building or upgrading modern chassis systems. This black spigot adapter bridges your Picatinny rail system with Arca-Swiss compatible accessories, giving you the flexibility to run gear across multiple platforms without fumbling with different mounting standards. Whether you're setting up a dedicated long-range rifle, a competition build, or a versatile multi-purpose platform, this spigot lets you swap bipods, bags, and supports quickly without tools.

Built from solid aluminum construction with a professional hard-anodized finish, the Aero Precision spigot is engineered to handle repeated mounting cycles and field use. The dual-interface design means you're not locked into a single accessory ecosystem—you can run Arca-compatible shooting bags, monopods, and bipod heads alongside traditional Picatinny-mounted gear on the same rifle. That flexibility matters when you're constantly refining your setup or managing an armory across different disciplines.

Aero Precision's reputation for tight tolerances and attention to detail shows in this spigot. The fit and finish are consistent, the matte black coating won't reflect light in the field, and it's compact enough not to add bulk where it isn't needed. If you're already invested in Aero Precision components or prefer their approach to modular rifle building, this spigot is a natural fit for your chassis-based platform.

Frequently Asked Questions

What's the difference between Picatinny and Arca-Swiss mounting?

Picatinny is the standard mil-spec rail system found on most rifles and AR-platform builds. Arca-Swiss is a dovetail interface common in precision shooting bags, monopods, and aftermarket bipod heads. This spigot lets you use both on the same gun by adapting between the two standards.

Will this work on my current rifle?

The Aero Precision Chassis Spigot is designed for rifles with Picatinny rail systems. If your rifle has a Picatinny rail—standard on AR-platform rifles, chassis systems, and many modern tactical rifles—this spigot will mount directly to it.

Can I use this with different bipods and accessories?

Once mounted, this spigot provides an Arca-Swiss interface, so you can use any Arca-compatible bipod, monopod, or shooting bag. It also retains Picatinny compatibility, giving you options.

Is this made in the USA?

Aero Precision manufactures products in the United States, consistent with their commitment to domestic production and quality control.
