This is a precision ball bearing designed specifically for. Luth-AR A2 rear sight bases. It's a small but critical component that ensures smooth elevation and windage adjustments on your AR-15. You'll need two of these per sight, and they're manufactured in the USA to tight tolerances.
The bearing enables the click adjustments that define A2 sight operation. Without quality bearings, your sight adjustments become stiff, imprecise, or binding. This component solves that problem at the source.
Luth-AR manufactures this bearing to specification, ensuring it works seamlessly within the A2 sight base assembly. The precision fit means your elevation and windage adjustments stay consistent through thousands of rounds. This is the kind of component that doesn't get noticed until it fails, which is exactly the point. Quality bearings stay silent and reliable.
This bearing is engineered specifically for Luth-AR A2 rear sight bases on AR-15 platforms. The precision fit is critical because even slight variances in bearing diameter or tolerance affect how smoothly your sight adjusts. You'll install two per sight base, and they're what allow those tactical adjustments to function properly.
Follow safe handling and manufacturer instructions. Ensure compliance with all applicable federal, state, and local laws.
