What a combo? Get started with your very own build. Our AR15 Stripped Lower Receiver is the only way to start your AR15 build. Made to Mil-Spec standards, our stripped lower receiver is second to none in quality and works with Mil-Spec AR15 parts & components. The A3 upper receiver assembly is made to mil-spec standards and includes a picatinny rail on the top, dust cover, and installed forward assist.
This combo also comes with a bolt carrier assembly is designed to work with any Stag 15 rifle, upper half, or barrel designed for right hand ejection in the either 5.56, .223, or 300 BLK. The salt path nitride process (also known as QPQ) creates a much harder surface that is, easy to clean, will run with less than ideal lubrication and resists wear for a lasting corrosion resistant durable finish.
