Heavy-Duty Buffer Tube

The included 6-position buffer tube is manufactured from durable aluminum and finished in black anodizing for corrosion resistance and long-term wear protection. Serving as the housing for the rifle recoil system and stock mounting interface, the receiver extension is designed to provide dependable fitment and compatibility with Mil-Spec adjustable stock systems. The six-position adjustment layout supports flexible stock positioning and shooter preference configurations.

Receiver End Plate and Castle Nut

The included Mil-Spec receiver end plate helps maintain proper alignment between the lower receiver and receiver extension assembly while supporting secure installation. The accompanying carbine castle nut threads onto the extension and locks the assembly into place, creating a stable attachment point for long-term use and repeated adjustment cycles. The castle nut is compatible with both Mil-Spec and commercial receiver extension applications.
