Pretty much any aperture sight will improve on any (other type of) open sight.
On my Marlin 795 (same sights as your 60), I put a TechSights front on, and a Williams WGRS-54 rear on. This was because at the time there were no TechSights for the Marlin. I used a TechSights front for a different rifle, per the recommendation from TechSights customer service. And I used the Williams rear because that is what was available at the time. Plus, my half-n-half setup cost less than a full setup of TechSights (which weren't available anyway, so it was a moot point). I had to file down my TechSights front a little to make it work with the lower Williams in the rear. But that took me all of 30 seconds to complete.
Aperture sights are SO much better than regular open sights. So my recommendation is to get aperture sights. TechSights are one example of aperture sights (and a good example, by the way).
