Home Forums Hunting & Shooting Gunsmithing fitting shooter and shortening a rifle Stock

The old school forearm length is useless for stock fit. With gun mounted the eye needs to be in the right place.

There is plenty of latitude in the elbow and wrist to accommodate a bunch of variables. You also have some latitude in scope mounting. If the thumb just clears the nose it will not in recoil and there will be blood if there is significant recoil. Obviously the CZ527 is not exactly a heavy kicker.

With the scope all the way forward in the rings I like about 4.5 inches between eye and ocular ring/lens. It should then be mountable at about 4" which is standard long eye relief for a scope.Just measure the distance and calculate subtractions to bring the face into the 4" area.

Adjustments may need to be made for the changes in mounting when the gun is shortened. Usually the form is quite a bit more relaxed and the head/eye will move back a bit.
