Mossberg Shockwave Brace Kit:

GG&G has chosen the most desirable and strongest components to upgrade your Mossberg Shockwave. From the most durable brace adapter found, to the softest and most comfortable grip on the market, this kit will allow for the installation of the coveted SB Tactical SBA3 stabilizing brace. The SBA3 gives the shooter the ability to quickly adjust the brace's length, on the fly, for rapid deployment.

The GG&G Mossberg Shockwave Brace Kit only adds an additional 4.25 inches to the length of the Shockwave Shotgun when collapsed.

ATF has determined that the Pistol Stabilizing Brace if used as designed, is legal to purchase, legal to own, legal to install and legal to use. Furthermore the ATF has determined that attaching a pistol stabilizing brace to a firearm does not alter the classification of the firearm or subject the firearm to NFA control.
