The Blaser mounting system itself provides an excellent quick mount platform for scope mounting. Now we can offer the same mounting system for a number of other rifles! The Osuma Blaser adapter converts a traditional scope mounting rail to a Blaser -style mounting system. By fitting the Osuma Blaser adapter on your rifle, you can even change sights in the middle of your hunting expedition without having to re-set the sight. The adapter is fastened with screws to the holes bored in the bolt body and fitting the adapter doesn’t require any special tools or skills.
