Re: Mercury Suppressor
Mercury recoil reducers have been used for 50+ years by trap shooters. If they didn't work, they wouldn't use them. In rifles with very light synthetic stocks, many times it helps balance them so they aren't so muzzle heavy. If imbedded in a butt stock, the reducer has to be securely fixed, so it doesn't move at all, which can be quite a 'trick' in stocks that have a 'foam' filling.
"Shoots real good!": definition; it didn't blow-up in my face.
