Abstract: Described is a locking stop mechanism for a riflescope that includes at least one rotatable reticle adjustment dial mounted on a scope body. It includes a stop member on the adjustment dial at a preselected position and a lock member on the scope body. The lock member is positioned to engage the stop member upon rotation of the adjustment dial to a preselected setting. The lock member is configured to prevent rotation of the adjustment dial in either direction when engaged with the stop member while allowing free rotation in at least one direction when the lock member is manually displaced and when the stop member is not engaged with the lock member at the preselected setting.

Abstract: A riflescope high speed, coarse and fine adjustment assembly that includes a riflescope with an erector tube located inside a scope body. Formed on the scope body is a mounting surface with a lead screw slot located adjacent to the proximal end of the erector tube. Located over the mounting surface is an adjustment plate with a perpendicularly aligned post member located thereon. Located inside the post member is a threaded lead screw with threaded head that connects to the post member and a lower non-threaded neck that extends into a slot formed on the mounting surface. The adjustment plate is affixed along its front edge while the plate's opposite rear section is detached and free to move up or down. Disposed over the adjustment plate is a cover plate with a fine adjustment lever that selectively rises and lowers the rear edge of the cover plate. Attached to the cover plate is a detent plate. Attached over the detent plate is a coarse adjustment dial.
