What a combo? Get started with your very own left handed build. Our A3 upper receiver Assembly is second to none in quality and is made to mil-spec standards. It 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.
