    Luth-AR 308 Ejection Port Cover Assy Accessory Compatibility & Recommendation Guide

    Product Compatibility Overview

    The Luth-AR 308 Ejection Port Cover Assy is a precision-engineered dust cover designed for AR-10/LR-308 pattern rifles. As a critical component, it protects the ejection port from debris, dust, and environmental contaminants, ensuring reliable cycling and longevity of your rifle. This assembly is compatible with standard DPMS/SR-25 pattern upper receivers, which are the most common in the AR-10 market. It utilizes standard mil-spec mounting hardware and spring mechanisms, making it broadly compatible with most .308 AR platforms.
