Whenever I change out the Gear Oil on my Harley (I use Amsoil brand 75-110 wt) , I hate the STINK of it! Gear oil is also way too thick and so sticky it will attract all kinds of crud. IMHO NOT a good idea for firearms!

There are sooooo many good "GUN OILS" made and marketed exclusively for firearms, WHY would you want to use Gear Oil on them??
