Thanks, they are real easy mods and these details make a nice difference in its looks.There is no need to repaint unless you want to, I didn't. Anything is possible, I personally have no desire to make a pop up sight on this piece. Wand Company could certainly have designed this with a pop up sight themselves even in switching to 'AAA" batteries but that would surely have driven up the price point. It's funny Wand Company released an 11th doctor sonic screwdriver that did not open then they re-released an opening version calling it the 12th doctors sonic screwdriver. Ironicly Peter Capaldi preferred to use it closed and it was even super glued shut at some point, his feeling was that flicking it open was Matt Smith's domain. Ultimately Peter Capaldi's 12th doctor got a completely new and different sonic screwdriver of his own before bowing out of the series.
