should have purchased one with the factory threaded barrel, they still come with the sights installed
don't know where you can get any type of slip over for the spotter weight barrels..may have to buy some universal ramp front sight of the correct height, and either have the barrel d&t for screws, or have it silver soldered on...talk to whomever you"re having do the work about specifics
