The System #1 is built around a hydraulic shock absorbing piston to reduce felt recoil. This piston is fully adjustable to handle a wide variety of loads from light skeet loads to the extreme magnums. With this versatility the system can be mounted on almost any shotgun or rifle.

To provide the shooter with added versatility the System #1 comes with a Hart Pad Adjustment System built into the unit. This allows the shooter to adjust the position of the recoil pad horizontally, vertically, or canted for a precise fit.

A key part of the system is the use of heavy 3/8 diameter guide pins and Frelon bearings. The guide pins are hardened to 60/65 HRC and have a surface finished of 8 Ra micro inches. This provides for long life and a low coefficient of friction. The low coefficient of friction allows the unit to operate in positions that other such devices would bind or lock up.
