This is updated review of Enidine Shot Shock Hydraulic Recoil Reducing Stock Tube.
This is very interesting product. Hydraulic buffer really works and reduces felt recoil. 36 gram birdshot still kicks hard but it is less painful. I would recommend using Magpul Enhanced Rubber Buttpad with this stock, this will make it even better.
Keep in mind that however common, mistakes do lead to accidental discharges. Lack of, or poor training will lead to mistakes being made. Careless behavior leading to an injury when a shooter knows better should be considered negligence and not be considered an accident caused by a mistake. When you know better and still do not follow proper safe handling procedures then you are negligent.
