I have 1 improved cylinder and 3 skeet chokes. Briley titanium chokes - Beretta Optima HP.

According to Briley's website:

"The Briley Titanium extended chokes are made from lightweight titanium material to reduce muzzle weight and utilize the exclusive Briley Spectrum colored bands for easy identification. The highly polished interior as well as the perfect internal geometry produce very consistent patterns and minimize fliers. In addition to their light weight, Briley Titanium chokes are easy to clean because carbon and wad plastic does not stick to titanium like conventional steel chokes. Not recommended for steel shot. Please note, titanium chokes to not have notches and will require the taper friction wrench."

Asking: $80/choke - shipped.
