Williams drill jig - Williams Gun Sight Scope Mount Drill Fixture

It’s well made but it only has one guide for drilling with the #31 or #28. It costs $167 delivered to my business (I’m a professional gunsmith) you would think for that price they could have included enough guides for all 4 bars since they included lock down screws for each bar but only one guide. The #31 utilizes the #28 guide for the actual tap to stay aligned properly but nothing for the larger size. Charge me a few dollars more and give me everything I need but it’s kind of ridiculous that you only get one guide for each drill needed. The other complaint I’ve got with it is when lining up to drill holes for the Mossberg 500 is only 3 holes lined up which left me needing to move jig to drill the last hole. It’s a good tool but it could definitely use some improvement to make it easier to use. I got the job done, however it took extra time and patience to find the exact center not once but twice instead. Instructions were minimal at best, so make sure you have a good caliper if you expect good results in return with this tool.
