Surecycle Benelli M4 12ga Magazine Extension kit +2 tube, spring and follower

Description

New old stock ( been around the shop for years and taken from package to photograph. )
Surecycle +2 magazine extension for the Benelli 12 Gauge Super 90 M4 shotgun
For Benelli M4
This is a plus two rounds / +2 extension with the tube, connection nut, spring and also a high visibility follower.
I
believe
this is the same as the new version other than they changed the connection nut , as it looks a little different.
Also, I my ship this in a smaller square box for convenience, but rest assure the spring will not be damaged.
