This is an original O-ring for the Silver Eagle model Sporter, 20ga. It is installed in the gas cylinder, in a channel just forward of the gas ports. On certain serial numbers, a second ring is installed on the metal fore end insert to ensure a shnug fit of the fore end. Before ordering, please be sure that the original is actually damaged or missing, since this part rarely needs to be replaced.
