The Luth-AR Modern A1 Rear Base Sight Assy W/Rapidex Knob is a purpose-built rear sight upgrade for AR-15 rifles, combining a familiar A1-style layout with a modern Rapidex windage knob. This assembly includes the rear sight aperture, windage screw, Rapidex adjustment knob, detent, detent spring, roll pin, and flat spring, giving shooters a complete kit to refresh or enhance their existing rear sight base.

Ideal for range use, training, and general rifle shooting, this sight assembly offers more precise and repeatable windage adjustments than a standard A1 rear sight while maintaining a clean, uncluttered sight picture. Its compact components install like a traditional A1 rear sight, making it a straightforward upgrade for most AR-15 platforms. Backed by Luth-AR’s reputation for well-made AR parts, it’s a practical choice for shooters who value consistency and solid craftsmanship.
