I don't know if I'm just special, but I always have trouble installing the magazine catch on AR lowers. Getting them threaded on just right can be a real pain, and using a pencil or a punch to press the button in while spinning the catch wasn't working very well for me. This simple print fixes all those problems, and will not mar or damage the finish of your lower or parts.
