I did have to drill holes. I used a Thompson Contender scope base, it has about the right raidus for the handi barrel in front of the chamber area. It is an easy job if you have a drill press and get a #31 drill and a #6-48 tap. I used a 2.5X NC star illuminated pistol scope, (NC Star also has a 2.5 to 7X that could be nice if you made one using a .223) I would call it a great night rifle under 50 yards, or a day time rifle in RF only areas. The barrel was shortened to 19 1/2 inches for packing and shipping reasons. Larry
