AR15/M16

Our selection of AR15 parts is broken into two categories to make finding what you are looking for quicker and easier.

Lower Receiver Parts

We have everything you need to build out that back end of your firearm. We offer action springs, buffer assemblies, buttcap screws, grips, and stocks. You can even purchase a full lower receiver parts kit to receive all lower receiver parts in one package.

Upper Receiver Parts

We offer upper receiver pieces related to the firing mechanism and nozzle barrel. From firing and extractor pins to uppers and magazines, our selection of AR parts for your forward firearm has it all. Similarly to lower receiver parts, you also can buy a complete upper kit in a number of styles.

At Sarco, Inc. in Easton, PA, we strive to carry the largest selection of AR 15 parts in the country. It doesn't matter if you need to replace a single grip screw or wish to rebuild a full weapon — we have the parts to make it happen. View our gallery of parts and kits on our website today!
