There is a guy on RFC, goes by "bone" that makes a very good copy of the #3 sight!!Have not had it to the range but hope to in a couple of weeks. Did a cleaning on it so the bolt now closes easy. The holes for the rear sight appear to not line up with the barrel. This model never came with a rear sight but had the Mossberg #3 peep. My spare #3 is part of my Mossberg peep sight collection so after gun shows start up I will be looking for another #3. Meanwhile I will mount a Savage #105 peep on it. It is a nice lite handy rifle. That rear sight just upsets me. The only good thing about it is that it is a Mossberg sight and can go into my stock. This Model 30 looks well used (very used) so don't expect it will shoot that well - hoping for a surprise.
