First Impressions of Luth-AR A2 Rear Base Elevation Knob Spring
The Luth-AR A2 Rear Base Elevation Knob Spring might seem like an insignificant part, but it’s a crucial component in maintaining the zero and overall accuracy of any AR-15 equipped with an A2 rear sight. Without it, your elevation adjustments become unreliable, leading to frustrating range sessions and potential misses in critical situations. Luth-AR, a reputable name in the AR-15 parts industry, offers this seemingly simple spring as a direct replacement to ensure proper function.
What prompted me to seek this particular component was a growing inconsistency in my A2-equipped AR’s elevation adjustments. The elevation knob felt loose, and my groups at the range were opening up vertically, hinting at a potential issue with the spring’s tension. Having encountered similar issues in the field before, I knew a worn or broken elevation spring was the likely culprit.
Upon receiving the Luth-AR A2 Rear Base Elevation Knob Spring, my initial impression was that of a small, unassuming piece of coiled metal. However, closer inspection revealed a clean, consistent winding and a uniform finish. It appeared robust enough for its intended purpose. Compared to a generic replacement spring I had previously tried, the Luth-AR spring felt noticeably firmer and more precisely manufactured. I chose this specific Luth-AR spring because of Luth-AR’s reputation for quality and the readily available positive reviews on their AR-15 components. My first reaction was relief – knowing I had a potential solution to my accuracy problem.
