XLR Mercury Recoil Reduction Weight Kit

The XLR Mercury Recoil Reducer is designed to fit inside all-aluminum XLR Buffer Tubes and is available for many past XLR Buttstock models and current. It instantly reduces the recoil of your tactical, hunting, or competition rifle by utilizing the unique properties of mercury liquid metal disperses energy generated upon firing. It also reduces recoil by adding an additional 25 ounces of weight (18.5 ounces if using the short tube) to your rifle. 

NOTE: Does NOT work on the carbon buttstock OR C-6 Buttstock. 


How the Mercury Reduces Recoil

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 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. Practical size limits spring-weight systems to using small moveable weights. The use of mercury allows us to increase the weight within the Mercury Recoil Suppressor while keeping overall size and weight within reasonable limits.


Contoured Weight: 25 Ounces

NOTE: If being used in a standard buffer tube a 1/4" hole will need to be drilled through in order to install the mercury tube correctly. If you have any questions please give us a call.
