I don't see why it can't be done, they hard chrome M-16 & M4 barrel bores. The chrome itself is so thin it shouldn't interfere with fit. If its a hunting rifle it may be a bit shiny in which case a dura-coat would be in order over the chrome. I think electroless nickle would be a better choice if you want corrosion resitance. It would be a dull grey. Maybe a coat of pink dura-coat over the nickle would add sexyness and attract chics, and I dont mean the fluffy, featherd little things. ::)
