ATTENTION MOSSBERG 930 JM PRO AND 940 JM PRO MODEL OWNERS: This GG&G Magazine Tube Extension WILL NOT FIT your shotgun!

IMPORTANT NOTICE: The GG&G Barrel Clamp makes contact with your barrel and the GG&G Magazine Tube Extension. This contact may damage/wear the finish on your barrel or mag tube during usage. We recommend using masking tape applied to the inside of the GG&G Barrel Clamp where it makes contact with the barrel. It is not advised to apply any tape to the inside of the barrel clamp that makes contact with the Mag Tube Extension.  Since GG&G Inc. cannot control the installation of this product, GG&G will not be responsible for any wear, blemishes, marks or damage that may occur to your shotgun.

Mossberg 930 Magazine Tube Extension Specifications:

  • Perfect for Military, Law Enforcement and Home Defense use.
  • Fits 12ga Mossberg 930 shotguns only.
  • Both the two shot and three shot GG&G 930 Magazine Extension Tubes are designed to be installed onto the Mossberg 930 factory 4 shot magazine tube. They do not replace the factory magaziine tube.
  • The two shot extension adds two additional rounds without increasing the overall length of the shotgun.
  • The front of the GG&G Mossberg 930 Two Shot Mag Tube Extension does not protrude beyond the barrel of a standard 18. 1/2" model.
  • The three shot extension adds three additional rounds and protrudes approximately 2 3/4" beyond the barrel of an 18 1/2" model. IMPORTANT: It's important that you realize that having your Mag Tube Extension protrude past the muzzle may cause carbon build-up, scoring or discoloring to the mag tube extension, especially if you are using a ported choke tube. GG&G does not warranty this type of finish damage to the extension.
