The Progressive Comfort recoil reduction system incorporates three sets of patented interlocking flexible buffers that absorb recoil at different stages depending on the strength of the cartridge charge.
By cutting away the outside of the stock, you can see the polymer system that includes 3 sets of fingers or blades. Each of these 3 sets of fingers has a different elasticity, and the load used determines which sets of fingers are used for maximum recoil reduction. The first set of fingers is very flexible for light loads, the second set a little stiffer for field loads, and the third set is optimized for heavy magnum loads.
