AR Rifles

Shop AR-15 rifles and AR-pattern firearms at RCS Outdoors. The AR-15 is America’s most popular rifle for good reason — accurate, reliable, endlessly customizable, and built on a platform with decades of refinement and a massive aftermarket. We carry AR rifles for hunters, competitive shooters, home defenders, and first-time AR buyers.

Why Choose an AR Rifle

The AR platform’s strength lies in its versatility. The standard AR-15 in 5.56 NATO or .223 Remington handles everything from coyote hunting to home defense to weekend range time, with mild recoil that makes it accessible for shooters of any experience level. AR-10 rifles chambered in .308 Winchester or 6.5 Creedmoor extend the platform to deer hunting and long-range precision work. The modular design means you can swap uppers, optics, stocks, and accessories to fit exactly how you want to shoot.

What to Look For

• Caliber — 5.56/.223 is the most common and most affordable to feed; .308, 6.5 Creedmoor, and .300 Blackout serve specialized roles
• Barrel length — 16″ is standard; longer barrels (18″–20″) for precision, shorter for home defense.
• Optic readiness — many modern ARs come optic-ready out of the box
• Accessory rails — M-LOK and Picatinny rails let you add lights, lasers, and grips
