I have the .308 A-Bolt II varmit with the boss system. It is a sweet shooting rifle!! But you definitely know it when you shootwithout ear protection.I have shot several deer with it. Only time I did not get ear ring was this year I was in an open field shooting prone. If your under ANY sort of canopy of timber, RING CITY [:'(].

IF your doing any sort of hunting. I would not reccomend getting a boss equiped rifle. There is nothing you couldn't do with a BOSSless rifle in the field.

Love the gun but not sure if the trade off is worth my hearing!![&o]
