a sight pin attached to the sight pin mount and engaged with the boss and the knob; and

a lock engaged with the frame;

wherein movement of the boss within the frame moves the sight pin laterally;

wherein the knob is in threaded engagement with the stem such that when the knob is rotated in a first direction the sight pin moves in first lateral direction; and

when the knob is rotated in a second direction the sight pin moves in second lateral direction

wherein when the lock is tightened, the frame clamps the boss to hold the boss in position with respect to the frame; and

wherein when the lock is tightened, a clamping action from the frame is transferred to the boss such that the boss clamps the stem to hold the stem in position with respect to the boss.

9. A sight comprising:

a housing;

a dial rotatably connected to the housing;

a slide member engaged with the housing such that as the dial is rotated the slide member is moved in a vertical direction;

a bracket attached to the slide member, the bracket having a pair of legs forming an opening;

an arm selectively and slidably received in the opening;

a scope head attached to the arm;

a lock knob engaged with the pair of legs such that when the lock knob is tight, the arm is prevented from moving laterally within the bracket and when the lock knob is loose, the arm is permitted to move laterally within the bracket;

a micro-knob engaged with the scope head such that when the micro-knob is rotated in a first direction, the scope head is moved in a first direction and when the micro-knob is rotated in a second direction, the scope head is moved in a second direction; and

a spring and ball positioned within a bore formed in one of the pair of legs such that the spring urges the ball at least partially into the opening;

wherein the arm has a series of indentations such that as the arm is moved through the opening, the ball will be urged into and out of at least one of the series of indentations.

10. The sight of claim 9 wherein when the ball is in one of the series of indentations, the arm is selectively held in position with respect to the bracket such that the micro-knob can be rotated to move the scope head.

11. The sight of claim 10

wherein one rotation of the micro-knob results in moving the scope head laterally a first distance;

wherein a distance between each indentation of the series of indentations is a second distance; and

wherein the second distance is greater than the first distance.

12. The sight of claim 9 further comprising a spring and ball positioned within a bore formed in an end of the arm and wherein the micro-knob has a series of dents such that as the micro-knob is rotated, the ball will be urged into and out of the dents.

13. The sight of claim 9

wherein the scope head has a post, the post having a marker;

wherein the post is located at least partially with in a bore of the arm;

wherein the arm has a gap formed therein such that the marker is visible through the gap and the post has markings proximate to the gap; and
