I just purchased a 20 ga benelli nova and I have a burris ff3 I want to put on it, I have the burris 336 mount also, I want to have it drilled and tapped for the 2 holes on that mount and use the 336 mount instead of using the 4 hole weaver base, just looks cleaner and will be lighter , and will sit down on top of the receiver. Will that be a problem with this gun, just wanted to check and see if anyone else has did this I didn't want to mess up a new gun. Thanks
