The GrovTec PAR 45 Degree Angled Rail (brand part no. GTSW321) is a black offset Picatinny rail section designed specifically for mounting a secondary sight, such as a backup iron sight or offset red dot, at a 45-degree angle off the primary optic. It gives a shooter instant access to a backup sighting system with a simple wrist rotation, without breaking cheek weld from the primary optic. GrovTec builds the rail with a low-profile mounting system that avoids adding unnecessary bulk to the rifle, and finishes it in a Type-III black anodized coating for long-term wear and corrosion resistance. It’s a straightforward way to add offset capability to an existing Picatinny-equipped rifle.
