Weaver Black Picatinny Offset Rail Adapter

The Weaver 99671 is a black matte offset rail adapter made for a Picatinny mounting system. Its purpose is to create an additional mounting position away from the main rail centerline rather than to hold a scope tube directly. The compact adapter format makes it a supporting optic accessory instead of a complete scope mount.

An offset adapter is useful only when both sides of the connection use compatible interfaces, so the existing rail and the accessory being added should be checked before installation. The Picatinny specification defines the mounting standard for this model. Its black matte finish keeps the adapter visually consistent with many common rails and mounts.

This is the only offset rail adapter in the batch, making it easy to separate from Weaver’s rings, bases, and fixed MSR mounts. Use it when the setup specifically needs an offset Picatinny position rather than another conventional ring height. For other choices to compare with Weaver 99671, browse optics and rangefinders.
