The Mercury Recoil Suppressor is made by C&H RESEARCH.

The MERCURY RECOIL SUPPRESSOR is your best buy in recoil reduction.

All recoil reduction systems use the inertia principle of moving a mass of weight within the gun to slow down and offset part of the apparent recoil. Most devices sold contain two springs and a lead or steel weight. Some claim to have hydraulic action, but are really just spring-weight units filled with oil.

The MERCURY RECOIL SUPPRESSOR works on a different principle . . . the moveable weight is liquid mercury, free to react instantly when the gun is fired.
