AR-10/.308 Lower Components include the internal and replacement parts used to assemble, maintain, or repair an AR-10 or .308 lower receiver. This category is intended for builders and shooters who need individual lower components rather than complete lower parts kits. These parts support proper function, safe operation, and long-term reliability.

Common AR-10/.308 Lower Components are used within fire control groups, buffer systems, and lower receiver assemblies. Black Rifle Depot offers lower components designed to support AR-10/.308 platforms while maintaining compatibility with common large-frame configurations.

What Are AR-10/.308 Lower Components?

AR-10/.308 Lower Components are the individual parts that control the operation and interface of the lower receiver. These components are commonly used for repairs, custom builds, or upgrades where a full lower parts kit is not required. Replacing worn or damaged lower components helps maintain consistent function and reliable performance.

Because AR-10/.308 lowers differ from standard AR-15 platforms, selecting the correct lower components is critical. Proper fitment ensures reliable cycling, consistent trigger operation, and safe firearm handling.


Common AR-10/.308 Lower Replacement Parts

This category includes items such as pins, springs, detents, safety selector components, bolt catch parts, magazine catch components, and buffer-related hardware. These small parts play a major role in the overall function of the rifle and are often replaced individually during maintenance or customization.

Having access to individual AR-10/.308 lower components allows builders to service specific areas of the lower receiver without purchasing a complete kit. These parts are commonly used by experienced builders and shooters who prefer precise control over their rifle setup.
