There is a reason that US Secret Service and the US Border Patrol selected Wilson Combat magazine tube extensions for their shotguns, it's because they are tough and they are reliable. Why not trust Wilson Combat parts on your next shotgun build. The Wilson magazine tube extensions are fully machined and come with a new high visibility follower, and high power magazine spring. Wilson uses only the best materials, shouldn't you?.
