I was told to try asking for help here, so here goes..
I am making a carry handle BUIS. I took the rear apeture off so I will be able to repaint the handle. When I put the rear sight back on, I couldnt get it back on and lost 2 ball bearings in the process.
So as a final resort and relief from frustration, could I be able to send my BUIS to someone who could replace the two ball bearings and put the rear sight assembly back on correctly?
Or does anyone know where I could just send my sight to and they could replace the partss and assemble it back?
