500:

Thanks for the suggestions. I have colored the front sight with a pearl white nail polish and it works great. Only prob is that 8 or 10 times out of the soft gun case and it starts to wear and discolor. Great news though. I just talked with Herman at Steyr/Merkel in Alabama & Merkel makes an aftermarket fiber-optic front sight for the 140-2. I just carefully drive out the exist sight and drive the fiber-optic back in and shoot the rifle, then sand the fiber-optic down until I'm back to "zero" at 50 yds. And, Herman suggested drilling and epoxying fiber-optic dots on the express sight "zeroed" at 50 yds like Merkel does on the 141's. Everyday brings something new........
