I have a removable rear sight that I fashioned for my Tulle and it may work for others. I got a new tang screw (which on a Tulle holds the trigger on). I bought a serpant head rear rifle sight. You grind off and flat file the dovetail wedge so the bottom is flat and then drill a hole in the base of the box that's left so it can be attached by the tang screw; make sure the screws head will fit down flush on the base. It is attached with the serpants head going toward your shoulder. Then I take the smoothy to range and shoot to determine and find the horizontal center. I use a #2 sharp pencil to mark the top and shoot. I keep erasing and marking and shooting until I have the center. All shoots are on a line going up & down. Mark the tang under the nose of the Serpant so the sight can be removed and replaced to vitualy the same position. (I tapped a dot with a punch and scribed some decorative lines.) Then, go home and, this is important ....Clean the weapon FIRST THING (lol). Then remove the sight; cut your Y, V, or Groove or what your rear sight plate picture is. Then go to the range and shoot to get the vertical center (Filing down either front OR rear sight) and you should be set at zero or close. Go home. Repeat previous chore. Remove the sight blue, brown or finish as prefered. When not on the smoothy, it's in the pouch. :m2c:
