Quality AR-15, AR-9 and AR-10 rifle kits available.
Our AR kits are packaged with everything you need to build a custom AR-15, AR-9, or AR-10/LR-308 rifle from the ground up, except for the firearm component: The stripped lower receiver (80% lowers are available as add-ons). Our build kits provide the most cost-effective way to own a quality AR-type rifle that includes only the parts you want -- minus the high prices you'll pay for a "name brand" rifle.
Why buy an off-the-shelf AR-15 and pay a premium, when you can build it yourself? Building your rifle allows you to choose only the parts and accessories you want. We make building your kit easy, too: Each kit's upper is assembled and ready to install on your lower out of the box. All you need to do is install the included lower parts kit in your fabricated 80% lower or stripped lower receiver (sold separately). Then hit the range!
Guide: How to Install The AR-15 Lower Parts Kit
Customize your kit! Grab a sling and optic or iron sights.
Our AR15 kits aren't just convenient. They're equal to or greater in quality than the typical "retail rifle". We partner with some of the nation's top gunsmiths and manufacturers to carefully piece together each build kit, ensuring MOA accuracy and utter reliability.
