An adjustable arrow rest including a mounting plate having a plurality of threaded apertures to facilitate securement to an archery bow. An L-shaped slide block is mounted for reciprocal linear adjustment in a vertical direction on the mounting plate by a first pair of cooperating dovetail guide members. A housing block is mounted for reciprocal linear adjustment in a horizontal direction along a second leg of the slide block by a second pair of cooperating dovetail guide members. The first and second pair of dovetail guide members are each provided with a worm drive screw to effect precise independent micro-adjustment in vertical and horizontal directions. A rotary sleeve is mounted for rotation within a cylindrical bore formed through the housing block. A torsional coil spring surrounds the sleeve and provides a rotational spring bias thereto. A support of an arrow rest support blade or arm is secured within the rotary sleeve. The arrow rest support blade is rotatable in a downward direction under the force of an arrow against the restorative spring bias of the torsional coil spring. The torsional coil spring may be wound in discrete angular increments by a spring adjusting wheel to vary the spring tension to accommodate various different arrow sizes and weights, bow weights and individual techniques.
