So I mounted up a set of MBUS sights on my new, and first, build. When I tried to adjust the front sight I found it bottomed out and extremely tight. Shortly thereafter the pins on the adjustment tool broke off into the notches in the set screw. Good news is that I was able to dig all the pieces out of the notches. Bad news is that I have no wrench and no working sight.
So here's my question: Not wanting to break another plastic tool, is there a metal one that I can get enough torque on to get this thing adjusted?
