This mil-spec castle nut is designed to secure a compatible carbine buffer tube or receiver extension to an AR-15 lower receiver. It is suitable for new firearm builds, replacement projects, repairs, and routine maintenance involving compatible AR-15 carbine buffer assemblies.
Constructed from steel with precision-machined surfaces, the castle nut provides a secure connection between the receiver extension and lower receiver when properly installed with a compatible end plate. Its standard notched exterior accepts an appropriate armorer’s wrench for installation, adjustment, and removal.
