I recently removed the sights on my stainless Omega. The screws I removed that plugged the scope base holes worked to fill in the rear fiber optic sight holes. I ordered a package of the slave screws from T/C for the front sight hole. You will need one of them to fill the front sight hole as it is larger than the scope base holes. They only come in blue to the best of my knowledge. I bought a spray can of matte grey paint, drilled a hole in a small block of wood the same size as the slave screw, just deep enough to cover the threads of the screw and gave it a couple coats of the matte grey paint. Now my front screw matches the stainless finish and the gun looks really sharp with the slick barrel. Good luck!
