The VISM FlipDot Pro Red Dot Reflex Optic is designed with multiple mounting options, including a Picatinny/Weaver rail mount, Glock MOS plate, spacers, and a rear sight dovetail mount for most Glock double-stack models. Additionally, its base is compatible with RMR micro dot sights, fitting onto slides machined to accept RMR micro dot sights. The Ruger 5.7 pistol does not feature a Picatinny/Weaver rail, Glock MOS plate, or rear sight dovetail mount compatible with the VISM FlipDot Pro. Therefore, this optic is not directly compatible with the Ruger 5.7.
