Redfield 70 peep sight help

[Whelen Ed]

I recently acquired a new to me rifle with a Redfield 70 Peep Sight. The problem I'm having is the aperture is so tiny I can't get a proper sight picture. I've read 1/8 Id is the standard for hunting but can't seem to locate any replacement. Any help or advice would be greatly appreciated. Tha ks!

Carefully drill it out one size at a time untill you get the sight picture you prefer.

I believe that sight has a screw in aperture. For hunting you can unscrew and remove the aperture which leaves an about 1/8" threaded hole. That seems really large but the eye naturally centers.

Thanks guys. I wasn't sure if I could drill it ,but I moved up a little at a time and got a much better sight picture. Thanks again for the advice.
