Complete The Look

The GG&G Beretta 1301 Tactical 2-Shot Extended Magazine Tube w/ Barrel Clamp provides you with two additional rounds. The 1301 2 Shot Mag Tube is easy to install as long as you have a working knowledge of how to break down your shotgun to perform maintenance procedures. The Beretta 1301 Mag Tube comes with the Beretta barrel clamp. No modification to the shotgun is required. This two shot Magazine Tube Extension uses the factory follower.

Why is the barrel clamp included in our package for such a short mag tube?

THE REASON? YOUR SAFETY!: Recent research of two shot mag tubes installed without a barrel clamp on the Beretta 1301 Tactical Shotgun, has indicated that the mag tube nut has a tendency to begin to rotate and loosen during the firing sequence of the shotgun. If undetected, the nut could loosen enough to potentially cause a catostrophic malfunction. To avert this potential we include, and strongly advise you use, the barrel clamp included in the GG&G package. Please notice that most of our competitors in the market place are also including barrel clamps in their mag tube extension packages for the Beretta 1301 Shotgun. You should seriously consider this issue prior to purchasing a mag tube without a barrel clamp.

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.
