Instructions Always make sure your firearm is unloaded and the chamber is empty. Remove the stock magazine release button by using a punch or dowel to press the mag release button below the receiver lower surface and turn the mag catch counter clockwise until it unscrews from the mag release button. Install the mag catch into the recess on the left of the receiver and place the spring on the threaded portion from the right side of the receiver. Screw the new Timber Creek Outdoors button onto the threaded portion of the magazine catch 2 rotations with the three tapped holes facing away from the receiver. Use a punch or dowel to press the button below the receiver lower surface and turn the magazine catch clockwise until the threaded portion is one turn past flush with the button head. Place the Timber Creek Outdoors AR Extended Magazine Release on the button so that the button fits inside of the recessed pocket and install the screws. Align the Extended Magazine Release parallel to the trigger guard before tightening the screws.
