Are you sure T/C discontinued? I had them put one on my PA hunter about 5 years ago, because the gunsmith told me that my warranty would be void if anyone but T/C did the work. I sent the rifle & they did it for me. But it will help tighten your groups, especially if your eyes are failing like mine. I hunted illegal I guess for a couple years before they made peeps legal, but I missed 3 or 4 deer before putting it on and was sick of doing THAT, let me tell you.
