The Kastle Group RMR-45 Offset Mount lets you add a red dot at a 45° offset position, so a spare optic or a second zero sits off to the side of your primary sight. It uses the Trijicon RMR/SRO footprint, so any red dot sight built on the RMR footprint can bolt to it. It is designed to work with Kastle's MICRO-226 and ACRO-226 optic mounts and attaches to the side of the mount. The angled position also suits shooting from compromising positions or around obstacles, where you need to manipulate the gun from abnormal angles.

The mount is machined from 7075 aluminum and finished in Type III hard anodizing, here in Flat Dark Earth. Kastle's mounts use industry-standard Picatinny rail compatibility, so the system installs on almost all modern weapons systems. It is listed with seamless Fortress integration, so it fits in with the rest of the Fortress Series optic mounts. It is made in the U.S.A. and covered by a lifetime warranty on machined mechanical products against defects in materials or workmanship.
