Robust Engineering & Features

Rock-Solid Interface: Simple yet exceptionally durable design that drops directly into your rear trunnion.

This adapter is a perfect fit for standard 4.5mm folding rear trunnion rifles and custom builds.

Required Hardware (Not Included):

The Mod-1 adapter requires a standard AR-15 buffer tube, a castle nut, and a receiver end plate/lock plate (if applicable to your specific tube choice) to complete the setup.
