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 attached 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. During use, the coarse adjustment dial is rotated for the target distance and then the fine adjustment lever is rotated which causes the adjustment plate to finely adjust the length of the lead screw.
