This is the precision rear sight base spring engineered for A2-style rear sights that use ball bearing assemblies. Double R Armory manufactures this component to match grade tolerances, ensuring consistent performance and reliable elevation adjustments across shooting sessions. The ball bearing design reduces friction and wear, allowing your sight to maintain zero over extended use.
This spring is built to match grade specifications, which means tighter tolerances than standard mil-spec components. That precision translates to smoother elevation adjustments and better zero retention. The ball bearing design is the key differentiator here. Instead of the spring binding or sticking during adjustment, the bearing surfaces allow the spring to cycle smoothly, reducing the wear that causes sight creep over time.
The ball bearing assembly in this spring reduces friction points significantly. Standard springs can develop flat spots or binding issues after extended use, especially in precision shooting where you're making frequent micro adjustments. This design keeps your sight functioning predictably, shot after shot, without the adjustment drift that frustrates precision shooters.
This spring is engineered specifically for A2-style rear sight bases that incorporate ball bearing assemblies. It's a direct replacement component, not a universal spring. Verify your existing sight base uses the ball bearing configuration before ordering. Standard A2 rear sights on AR-15 platforms use this same interface, making this a straightforward maintenance part.
Follow safe handling and manufacturer instructions. Ensure compliance with all applicable federal, state, and local laws.
