First Impressions of Luth-AR A2 Index Elevation (Wheel)
The Luth-AR A2 Index Elevation (Wheel) is a seemingly simple component, but one absolutely critical for achieving accuracy with an A2-style iron sight. The Luth-AR name, while not always the flashiest, often implies a focus on functional, mil-spec-adjacent parts. For just over five dollars, this little wheel promises to restore or upgrade the elevation adjustment of an AR-15, and that’s a promise worth exploring.
My need for this product stemmed from a recent AR-15 build where the original elevation wheel was damaged. The markings were worn off, making precise adjustments guesswork at best. The Luth-AR A2 Index Elevation (Wheel) presented itself as a cost-effective and readily available solution to restore functionality and precision to my rifle’s rear sight.
Upon receiving the Luth-AR A2 Index Elevation (Wheel), my initial impression was of a basic, utilitarian component. The black finish appeared even, and the molded plastic seemed durable enough for its intended purpose. Compared to some aftermarket target knobs that offer tool-less adjustments and finer increments, this one is decidedly more mil-spec. I chose it over adjustable target knobs because I prefer to maintain the original A2 aesthetic and function.
My first impression was cautiously optimistic. It appeared to be a well-made replacement part that would solve my problem. Considering its low cost, my expectations were realistic.
