Remington 1100/1187 Extended Parallel Section Choke Tubes. I brought these chokes back from USA. As well as having an extended parallel section to give the shot longer time to settle, the chokes have external tool engagement slots so the shot  is not disturbed on leaving the barrel, thus maintaining the best pattern possible. The choke bore sizes from largest to smallest are. 693" .688" .679" inches, which will give dense patterns on long distance shots.

Only one of these chokes has been used, so two brand new.

These were very,very expensive. Included in this sale 3 Extended Chokes & 1 Fitting Tool.

The red lines on the tubes indicate if the choke has become loose.
