AR Parts & Accessories

Once you've got your 80% lower built, it's time to personalize your rifle. The great thing about the AR-15 platform is everything is plug and play, and you can customize as much or as little as you see fit! With the AR-15, almost everything is able to be changed at home with no special tool besides what you already have in your toolbox! SO whether it's putting on a new stock, a new pistol grip, or finding the best sights and optics to fit your rifle, we have everything in stock at Modulus Arms.

Any questions? Contact our world class customer service team at: We're all shooters, so we love answering questions when it comes to how to build out a rifle, or what we think works best!
