Briley adjustable rear sight for auto shotguns is designed to assist the shooter when having to shoot targets with slugs at long distances. It has an express style rear blade with a small notch. This allows the shooter to still see the rib while shooting shot at closer static or aerial targets. Download instructions and drawings for more information.
Narrow Rib Sight Reinforcement Insert
The rear sight can also be fitted to narrow ribs i.e. ribs that are smaller than .250¨ in width but
not narrower than .235¨. This will require the use of a narrow rib sight reinforcement insert.
The insert is required to afford the elevation pin of the sight additional support. The inset will
require an additional slot be cut in the rib together with a tapped hole.
