The Rival Arms stud mount adapter is a straightforward piece of AR platform hardware designed to bridge your existing stock or forend to standard mounting points. If you're upgrading furniture on your AR-15 or AR-10, swapping between different stock profiles, or trying to use aftermarket accessories with legacy components, this adapter provides the mechanical interface you need. It's machined from 12L14 steel and finished in black oxide—a durable, corrosion-resistant coating that stands up to field use without fuss.
Built from 12L14 steel, this is a workhorse material: machinable, tough, and reliable. The black oxide finish protects against rust and gives it a low-profile matte appearance that won't draw light. This is the kind of part that does its job quietly—no flash, no marketing, just solid engineering that lets you focus on getting your rifle the way you want it.
Whether you're assembling a precision rifle, a duty gun, or a practical hunting setup, having the right adapters and interfaces in your parts bin means you can mix and match components without compromise. The stud mount design keeps things simple and repeatable. This adapter is a go-to choice for AR builders and gunsmiths who need reliable hardware that fits properly and holds zero.

A stud mount adapter provides a mounting interface between your AR stock or forend and aftermarket accessories or furniture. It ensures compatibility between components that might otherwise not align or fit together securely.
This adapter is designed for AR platform stocks and forends. Confirm your specific stock or forend model matches the stud mount interface before purchasing to ensure proper fit.
12L14 steel is chosen for its machinability, strength, and durability. It machines cleanly for precise tolerances and holds up reliably under the stresses of normal rifle use.
Black oxide is a proven corrosion-resistant finish that protects the steel underneath from rust and wear. It's standard on quality AR parts and holds up well in the field without special maintenance.
