That was probably my post you are talking to. Both of my billet lowers were tight and I don't just mean new tight. One was so tight a hammer could not get a mag in there. I talked with Paul and to his credit, no questions, he took care of it. Both lowers are now operational and work fine. I would call him and see what he can do for you. Some shops get fed up and it becomes all about the attitude. I have personally not seen this from him.
