Welcome to designing your very own AR15, filled with whatever we offer for our builds and this will be designed by you. You can still reach out to us for help though if needed. Please keep in mind “Builders Notes”. If there are notes listed in the parts page, then you need to read this to make sure parts are compatable with one another. These are things I’ve learned over the years and I want to help you build the gun of your dreams. So pick your parts for your build and feel free to contact us with questions.
