I've fitted an HW pistol stock to this new model HW45 and although I have the foresight raiser, it doesn't fit on the new style foresight so I'm looking at fitting a red dot or similar instead- or possibly a bug buster style scope. The scope rails seem to be an unusual size and wont take my existing red dot sight with integral rails. Can anyone assist and recommend what mounts or sight I need to fit the scope rails?

Thanks
