Skip the parts pile. Start with the right upper.
The Sugar Weasel 16″ Complete Upper gives you a straightforward way to bring Q engineering and performance to an existing rifle build without starting from scratch.
Built around the Sugar Weasel platform, this complete upper is designed to stay lightweight, balanced, and dependable while eliminating the guesswork that comes with piecing together individual components.
