After reading the reviews and some with issues I had a gun smith install the sights on my TC Renegade .50 cal. Sights were installed with no additional holes needed to be drilled and tapped on the rear sight. He did secure the front sight with an added screw to keep it secure. These sights are a real game changer!
Front sight worked fine but as stated before by another buyer the rear sight does not match the stock rear sight holes. For it to work you would have to have the barrel tapped. This sight is much shorter than the original TC rear sight.
Front site fitted well after installation. Rear site was half the length of the original and the two new screw holes did not match up with the original holes which are further apart.
I'm just a casual shooter with less than 20/20 eyes so I wear glasses. I purchased this for my Traditions Hawken 50cal. I must say this has certainly improved the sight picture for me. I have not shot the gun yet but I can see the sights much better. The biggest issue was fitting the front sight. I expected this as all dovetails are not created equal. So you may need a lot of filing of the front sight. The rear sight mounted ok but I had to use the rear mounting hole and the original screw from the Tradition's sight. All in all it seemed to work out ok.
