The Perazzi RSR is available in 12 or 20 gauge. The first high vision design. Released 2012. This was my first exclusive and unique rib design allowing the shooter to see much more of the target and have a far greater peripheral vision. The RSR is now very popular and once accepted and trusted it offers a far superior target vision than any other shotgun currently available. The head position with the RSR is raised approximately 5-6m above the breech face but although hard for some to accept, with this vision it will not shoot high. As you can see in my testimonials, this design really works and will generally give the shooter between 5 and 10% advantage over the SR1. Five more targets hit out of 100 ? That is well justified.
