I just found in my reloading supplies a Receiver Sight (Used) for a Ruger M77 and Ruger #1. This sight came from New England Custom Gun Service Ltd with a sales sticker of $89.95. I will sell it for $45.00 including P/H. The description is as follows: Fully adjustable for windage and elevation. NO gunsmithing required. Sight includes two (2) apertures (.093 and .125 holes). Thanks for looking. :lol:
