Almost seems like the rail screws were bad or not tight; I tried to get some factory service for my Tx3 but its been weeks and nothing but the original auto response email that we will get back to you shortly; I ended up fixing my chamber issue my self.
I would remove scope and then rail and see if those factory screws could be removed and replace rail and screws; I would verify the threads are ok for the mounting screws
I purchases a mountain tactical picatinny rail (contact them to verify it works for CTR) with which has steel insert to put any recoil on the insert verses screws alone; got mine at midway usa vs direct from manufacturer
