a cylindrical member having a first open end and a second end, said cylindrical member having holding means of an appropriate size to match the holding means on the support ring of the telescopic sight;

a knob affixed to the second end of said cylindrical member in a freely rotatable and co-axial position with respect thereto;

screwdriving means affixed to said knob and positioned along the central axis of said knob; and

biasing means between said screwdriving means and said cylindrical member, said biasing means urging said screwdriving means inwardly toward the open end of said cylindrical member.

2. The knob of claim 1 wherein said cylindrical member and knob are provided with indicia for indicating rotational position.

3. The knob of claim 1 wherein said knob is fabricated from anodized aluminum.

4. The knob of claim 1 wherein said biasing means rests on a shoulder located in the second end of said cylindrical member and also resting on the upper surface of said screwdriving means.

5. The knob of claim 1 wherein said ring and cap are threaded.

6. The knob of claim 1 wherein the second end of said cylindrical member has a cover portion with a central opening having a raised wall surrounding the central opening and wherein said knob is a cylindrical member having an open end having an inside diameter sufficient to permit said knob to fit over said raised wall and said knob having a closed end to which said screwdriving means are affixed.

7. The knob of claim 6 wherein indicia are positioned on said cover portion and an indicator mark is positioned on the outer side wall of said knob.

8. The knob of claim 6 further including a second cover portion located at the upper extremity of said raised wall, said second cover portion having an axially positioned opening, so that said second cover portion forms a base for said biasing means.
