Zero stop adjustable rifle scope
First Claim
1. A rifle scope adjustable zero stop mechanism that fits into hole formed in a turret and used to adjust the vertical position of the rector tube inside the rifle scope, said adjustment mechanisms comprising:
- a. an adjustment body with a lower threaded section that connects to a turret, said adjustment body including a longitudinally aligned threaded bore and a central cavity including a plurality of longitudinally aligned splines formed therein;
b. an adjustment bolt having a threaded upper section end and a threaded lower section, said threaded lower section connected to said threaded bore in said adjustment body, said adjustment bolt being longer in length than said adjustment body so that when said threaded lower section is connected to said threaded bore, said lower section extends downward and contacts a rector tube inside a rifle scope and threaded upper section extends above said adjustment body;
c. a stop ring having a threaded bore that connects to said threaded upper section of said adjustment bolt;
d. a lock ring having a threaded bore that connects to said threaded upper section on said adjustment bolt and above said stop ring;
e. means to lock said lock ring and stop ring together on said threaded upper section on said adjustment bolt; and
, f. a cylindrical outer cap aligned vertically over said adjustment body, said upper section of said adjustment bolt and said stop ring, said outer cap;
g. means to connect said outer cap to said lock ring; and
, h. whereby when said outer cap is rotated, said adjustment bolt is rotated inside said adjustment body to a desired zero stop position, said lock plate is rotated over said adjustment bolt until said lock plate and stop plate are adjacent and said means to connect said lock plate and said stop plate is used to lock said lock plate and said stop ring.

Abstract
A “zero stop” rifle scope adjustment mechanism that allows a user to establish the “zero point” at any point in the scope range, and still maintain ¼ minute clicks and with unlimited rotations of the adjustment knob. The mechanism includes a T-shaped adjustment bolt that is vertically aligned inside an adjustment body fixed in position on the turret of the rifle scope. The adjustment body includes a small threaded central bore to which the adjustment bolt is attached. The adjustment body also includes an upward cavity with splines formed on the inside surface. When assembled, the threaded upper section of the adjacent bolt extends above the top surface of the adjustment body. Disposed longitudinally and locked in position over the threaded upper section of the adjustment bolt and around the adjustment body is an index dial. Attached to the threaded upper section that extends above the index dial is a stop ring and a lock ring that are selectively locked together on the upper section of the adjustment bolt. A tab element is formed on the top surface of the index dial body which is engaged by a complimentary-shaped tongue member of the stop ring which locks the index dial body and stop plate together to prevent further downward rotation of the stop plate over the body. An outer cap is then longitudinally aligned and inserted over the stop ring, lock ring, index dial, and the adjustment body. The outer cap includes locking screw which when tightened, is forced against the lock ring to lock the outer cap thereto.
