My trigger guard is loose to the point of rattling when touched. I was going to try to replace it with a Magpul MOE trigger guard. Reading the installation instructions that came with the MOE, nothing mentions that one of the pins dose not go all the way through the lower receiver. How do I get that pin out? It looks like there is a smaller pin that is perpendicular to the pin in question. I am assuming that the smaller pin is holding the other pin in. Thanks Wanna kill these ads? We can help!
