Strike Industries Mag Release for CZ EVO, Black SI-CEVO-MR The Strike Industries Magazine Release for the CZ Scorpion EVO is a lightweight" high-strength polymer solution that enables the user to depress the magazine release utilizing only one hand. Whereas the original design requires two hands to disengage a magazine" the Strike Industries Magazine Release has added fins on both sides of the trigger guard that allow the shooter to use their shooting finger to hit the release" freeing the other hand of that burden and allowing for overall faster reloads. Quicker reloads lead to more rounds on target in a shorter amount of time.
