Just an idea. Check out the thread on diamond front sights. Read it all the way through and pay special attention to Carpet Sahib and his experience will perhaps help. See page two here, diamond front sights. I'm saving up for one to fit my Valmet 9.3. It may help to brighten the image you see from the front sight and to put it on the target through a ghost ring sight. That's all I do with the ghost ring on my Marlin 45-70. The eye centers the image automatically. I use one on 22 LR to 45-70. Monday some squirrels are going to find out about that. Good luck. Rustyzipper.
