In my opinion the more you spend on a bore site the more money you will waist.
It simplifies getting on paper I suppose but how often are you putting new scopes on? Looking down the bore gets you 95+% of the usefulness of a bore site. You can't substitute shooting and fine tuning either way.
But hey if you want one who am I to tell you otherwise I suppose. Just throwing my opinion in where it isn't really needed I guess
