I just read your post on the other thread and realized that you wanted to remove just the "leaf" and NOT the entire rear sight assembly.
I think that would probably be tough to do without damaging the entire sight assembly, but I can see the cosmetic downside of having a big ugly empty dovetail slot cut in your barrel if you do remove the entire sight assembly.
An option might be to do the full remove and then cover the empty dovetail slot with the weaver scope mount base (http://www.taurususa.com/products/carrifsmb.cfm). This would cover the dovetail slot, give you an unimpeded view of the iron sights and offer the option of later adding a scope if you wished.
Cheers,
PS - apologize for the "cut and paste" links, but not sure how to do a hot link to a message.
