Yes it is. I screenshot-ed your post and saved it my 362 anniversary folder. Thanks for sharing that. Does Crosman even have a part # for the sight? Or for that matter, the modified breech that it works with?
I was curious about the Williams sight on the legacy for another project…below is reply from Williams..That is a custom sight we make for Crosman under a contract. Our part # for it is #686773. You may be able to source one from Crosman directly, but it is not available on our website
