The Hyskore Dual Damper Machine Rest is a precision sighting tool that will provide maximum repeatability. Over 80% of all center fire rifle shots are made from guns in the .30 caliber range on down, therefore, this rest is designed to progressively absorb the recoil pulse from 5.56 / .223 up to and including .300 Winchester Magnum and .338 Winchester Magnum cartridges. The rest features surgically precise and user friendly windage and elevation controls. If you step back and take a look at the center fire rifles that are actually shot in this country you would find that 80% or more of the shots made are from rifles in the range of .223.5.56 up to and including the .300 Winchester and the .338 Winchester Magnums. Guns larger than that are much more expensive to shoot and generally speaking have recoil that discourages repetitive shooting. With that thought in mind Hyskore designed the dual damper rest to be able to progressively absorb the recoil pulse on the above mentioned guns. The objective of this rest is to provide absolute maximum repeatability from shot to shot. This means that once a gun is properly mounted in the rest and the rest is properly secured to a table or platform that does not move it will repeat shot after shot whatever the gun and ammo combination is capable of producing. If the rest is mounted, as previously mentioned, and you have a 1 M.O.A. gun / ammo combo the rest will repeat at 1 M.O.A. If you have a 3 M.O.A. combo expect the rest to repeat at 3 M.O.A. The rest will not make a 3 M.O.A. gun produce results at 1 M.O.A. â€“ Sorry! In order to achieve this degree of repeatability precision engineering and components were required. There are two N20 compression dampers that progressively absorb the recoil pulse and return the gun to battery. The compression dampers are fixed to the lower frame in the gun carrier assembly. The lower frame incorporates two longitudinal chrome plated shafts and the gun carrier assembly has four precision linear bearings that ride along these shafts. The windage adjustment, which can be operated from either the left or right side, uses the same technology. There are two linear bearings that ride on two chrome plated shafts to ensure a precise and smooth adjustment. The elevation can be operated by either hand via a capstan style knob which moves the forward gun support up or down and this assembly can be locked in place with a T handled bolt. In addition, in order to remove any possibility of shooter induced motion contamination the set is equipped with a remote hydraulic trigger release. Although the rest is primarily designed for a hands free calibration of gun, sight, and ammunition, the rear vise assembly can be removed exposing a platform for a rest bag for use at the range. The rest is designed to remove the variables for sighting calibration. If, at the end of the day, with the gun out of the rest, the results are not the same as the results with the gun in the rest the focus needs to move to operator error.
