I got my Meprolight sights today and got them installed. But, my 3/16" nut driver wont fit down into the hollowed out area surrounding the 'bolt' provided with my Meps. I got it screwed in all the way with my pinky finger, but I want to take it back out, put some loctite on it and tighten it a bit more with something other than my finger.
How did everybody else tighten their front Mep sight?
