Worked for my 1950s Remington 721
The product is great and works well, but they need to write down some instructions maybe tell what size drill bit to use or if you want a glue to be used with it. Would really save a ton of time and guessing. Only not giving 5 stars because of that. I would rather be charged an extra buck or two and have it come with a cheap drill bit of proper size and marked out depth.
