This is a one piece aluminum sight base for mounting a red dot sight to the Sig Sauer P320 X5 pistols. It uses the R1 dovetail slot to mount the sight to your slide and is bolted through the slide. Hard anodized for a long service life.

- Mount slides in from the slide like a dovetail instead of dropping in from the top. Do not file mount for installation.
