    The only 1-piece I could find for my old round top, tang safety M77. I have been searching for this for years, Perfect fit, and very sleek. Highly recommend to bed this once you get it. Thank you so much, Cameron!

    Fits PERFECT! Oddball pattern (thanks Ruger ) that this site was the only place (in the world?) that can be purchased from that you do not have to drill your own holes into :)
