ABSTRACT:
An archery bowstring release comprises a base grip member which is held vertically in use, the base grip member including an interior vertical cavity which intersects a slot which opens to three sides of the base grip member. A body member is slidably inserted into the slot and pivotally held by a fastener which is inserted through the vertical cavity. The body member includes an upper and a lower flange which extend toward the bowstring. A bowstring catch lever including a bowstring retaining hook is pivotally attached between the flanges at the forward end of the body member. A pawl lever is pivotally attached between the flanges; the pawl lever including a forward branch which selectively locks and releases the bowstring catch lever, and a rearward branch which extends into the slot in the base grip member and is pivotal to extend out one of the sides of the body member. A tip grip member is pivotally attached to the base grip member about a horizontal axis. When an archer grips the base grip member and tip grip member, the tip grip member will contact the pawl lever, which will lock the bowstring catch lever to retain the bow string; when the archer relaxes the grip on the base grip member and tip grip member, the pawl lever will be allowed to pivot to release the bow string.
