BRL...I use filler screws all the time, especially on rifles with low power scopes which show the front sight. On most rifles the screws that you take out to mount the scope are usable as filler screw out on the barrel when you remove the sights. I have the sights off a 7600, 7, and a 94 Timber Carbine and filled with the screws from the top of the receiver. I like the look too. DL
