Picatinny Shim set with 3 sizes for offset correction

This shim set is designed to achieve optimal alignment for red dots, scopes, and other accessories, accounting for the fact that different accessories can have varying inherent offsets.

In addition it can also create a controlled offset for improved ergonomics. Many competing Picatinny rails are marketed as 22mm but are often 21.2mm, causing 22mm optics to sit off-axis. This set ensures a perfect, fit.
