The Luth-AR A2 Rear Sight Assembly kit is a professional-grade component designed for shooters who demand mil-spec accuracy and repeatability on their AR-platform rifles. This complete kit is specifically tailored for A2 upper receivers, making it an excellent choice for both building a rifle from scratch and upgrading an existing platform.
The assembly includes the UR-29 Base Lug, UR-27 Aperture, UR-28 Spring, and UR-26 Windage Screw, all precision-machined to tight tolerances for zero shift resistance during firing. The aperture design enhances sight picture definition, while the windage adjustment mechanism allows for repeatable 1/4-inch click adjustments at 100 yards, enabling users to fine-tune their specific load and barrel combination.
Ideal for AR builders, armory personnel, and shooters seeking a drop-in rear sight solution, this kit requires basic mechanical assembly on a compatible A2 upper receiver, making it accessible for users without extensive gunsmithing expertise.
