I am haveing a heck of a time getting the screw out of the back side of my magazine release button. Torqued two of my Chapman bits and the head of the screw too. WHAT AM I DOING WRONG!!! I want to take the mag release button out to replace the trigger with a match trigger. Thanks for any and all imput. Jay

its not a screw, depress the release and rotate a quarter turn.

They make it look like a screw just to mess with you - take a screwdriver bit, or a short screwdriver, and place it in the slot - they with a gentle hand, push the magazine release in slightly - feel around a bit with the screwdriver, it will turn a partial turn and then the unit will easily come apart. No real force is required - just a feel.
