GG&G 3-Shot Magazine Tube Extension for Mossberg 930 12ga Black

GG&G 3-Shot Magazine Tube Extension for Mossberg 930 12ga Black. The GG&G Mossberg 930 Magazine Tube Extension utilizes an innovative coupling system that actually pulls the follower and spring forward towards the shooter which in effect causes the two extended tubes to "fuse" together. This patented GG&G innovation has proven its worth in the brush and in the fields. The GG&G Mossberg 930 Magazine Tube Extension w/o Mounting Holes is redesigned to fit the factory magazines with single round magazines but it will fit any 12 gauge shotgun with a flush or ramped magazine well. This GG&G innovation has also been used in a number of handgun and rifle competitions. Originally designed for military and special operations units this design has found its way into law enforcement and competition circles. It has also been used in a number of competitions against much larger calibers. This design has also been used in a number of law enforcement disciplines including FBI I.C.A. FBI Academy US Marshalls and several others. It has also been used in a number of re-enactments. This one has just been redesigned to incorporate an anti-rotation spring mechanism that is much easier to install and service than the original design.
