The Battle Arms Development Authelite (brand part no. AUTHELITE-SET) is a lightweight billet AR-15 receiver set finished in black, pairing a matched lower and upper receiver machined for reduced weight without giving up billet strength. Rated for multiple calibers, it’s built for shooters who want a lighter overall rifle without stepping down to a lower-quality receiver. Because the set includes both receivers machined together, builders get a matched pair rather than fitting components from different sources. It’s a strong option for a lightweight custom build where every ounce matters.
