Hastings Metro Barrel Extension - 12ga Only

The Metro system was developed for shotgun shooting in areas or when noise is not desirable. As a secondary effect, the Metro system will reduce felt recoil by as much as 80%.  When used with special subsonic ammunition, developed by Federal Cartridge, and eliminates the need for hearing protection. When fired, the Metro extension won't even set off hearing sound reduction equipment. The decibel readings are about 72db when using subsonic ammunition.  When fired with regular ammunition, the decibel readings are about 151db.  We recommend using Federal, Winchester, or Backridge subsonic ammunition.

Remove the shotgun's choke tube and install the Metro extension. Then, add the choke to the muzzle of the Metro extension, and you're all set to shoot.  The Metro system is a barrel extension that is specially ported to reduce muzzle noise by half. The 32" extension installs easily in seconds by threading on in place of a choke tube. No modification to the gun is necessary, and the Metro will even accept your gun's original choke tubes.
