I wanted a rear peep sight for my 92 but prefer to have windage and elevation adjustment. This is what I did for my rifle - maybe it will help somebody else looking for another sight option. I bought a Williams WGRS series peep sight for a Winchester Model 70 rifle. It doesn’t matter what rifle is intended for but the Model 70 sight has a similar mounting surface radius and a thick enough base to allow for machining to the correct radius to match the 92 bolt. The sight is screwed into a threaded plug in the safety hole. The sight also required clearancing to not interfere with the locking lugs when the action is closed.
For the barrel sight dovetail, I bought silver heat to harden clay and used it to fill the dovetail. I used a heat gun to harden it. Not the prettiest or even very durable solution but will do for now. I may try some model paint on the clay to get a better match to the barrel.
