Drop-In Insert Temporarily Reduces Mag Capacity
Hard polymer insert snaps into the floorplate to limit capacity for sporting or hunting applications. Installs easily without tools and requires no permanent alteration of the magazine. Will not make a banned magazine legal, as capacity reduction is not permanent. Minus 10 reduces capacity by 10 rounds.
