Product Description

Upgrade your Ruger® Mark™ Series pistol with the TANDEMKROSS Shadow Mount V3.0, a streamlined optic mounting solution designed for clean, low-profile red dot installation.

Unlike traditional Picatinny rails or bulky clamp-style mounts, the Shadow Mount V3.0 allows compatible optics to mount directly to the receiver for a lighter, sleeker setup.
