Claim:
A firearm support assembly comprising a frame of general horizontal orthogonal configuration, thereby comprising mutually attached longitudinal and lateral components; a front support; and a rear support; the front support comprising a cradle in turn comprising a generally horizontally disposed firearm barrel rest supported upon a downwardly extending neck; a vertical extension disposed by attachment to the frame; and a vertical positioning sleeve and set pin subassembly wherein the height of the cradle is adjusted and rigidly emplaced along a vertical portion of the frontal support; the rear support comprising a longitudinal positioning sleeve and set pin subassembly wherein the rear support's disposition is adjusted and rigidly emplaced along the frame's longitudinal component; a maximal force-attenuating third class lever vise comprising a fixed plate; a movable plate; a retraction bolt; a fulcrum-pivot; an elongated coil-spring; and a lag cylinder; wherein the fixed plate and fulcrum-pivot are attached to the sleeve of the longitudinal positioning sleeve and set pin subassembly's in lateral opposition to one another; the coil-spring is biased to force the fixed and movable vise plates apart and the retraction bolt thereof is longitudinally disposed within the coil-spring; the lag cylinder is disposed by rotable emplacement within the a lag cylinder seating tunnel disposed in turn within the movable plate generally parallel the assembly's longitudinal component; and the cylinder is configured in turn with a threaded diametric tunnel within which the retraction bolt is caused to interthread, whereby the movable plate's uppermost extremity is caused by reason of the screw retraction principles to circumferentially tilt inward and outward upon the bolt's respective advance or withdrawal.
