High-end, spring piston rifles with twin pistons opposing each other rather than moving in opposite directions as in Giss patent airguns manufactured by Dianawerk where one piston is a dummy. The opposing action eliminates almost all recoil and intensifies power. Each piston has a pair of springs, the total of four springs gives up to 650 lbs. loading.
