GG&G developed the Shockwave Flashlight Mount specifically for the Shockwave because the foregrip of the Mossberg Shockwave is a reconfigured version of Mossberg's 590 foregrip. Our 590 flashlight mount which is similar" is a hair too close to the foregrip" so if you own one of the new Mossberg's and need a flashlight mount" this is the one to get!

Features:
Installs easily
Manufactured specifically for the 12ga Shockwave, will not fit the 20ga Shockwave
Ambidextrous design
Rail measures 1 ¾” long
