Beautiful piece of wood. That sight if you notice hash marks on the numbers, start at the bottom and push the right side elevation button as you are pushing the sight forward you'll feel it click then push the left side button and so on, right left right left. it graduates at 50 meter increments. It's the only sight iknow of that does this. The K98 does 50 meter increments but only has one button. NICE GUN. GOD BLESS YOU! GOD BLESS AMERICA!! GLORY BE TO GOD!!! IN JESUS NAME WE PRAY!!!!!!!
