    Ruger Harrier 5.56 NATO AR-15 Accessory Compatibility & Recommendation Guide

    Product Compatibility Overview

    The Ruger Harrier 5.56 NATO AR-15 is a modern sporting rifle built on the AR platform, chambered in .223 Remington/5.56 NATO. It features a 16.1" threaded barrel (1/2x28 thread pitch), an M4-style collapsible stock, and a free float M-LOK handguard. These features ensure broad compatibility with most AR-15 accessories, including muzzle devices, optics, grips, and tactical enhancements. The M-LOK system is a current industry standard for accessory mounting, offering flexibility and secure attachment for a wide range of gear.
