Regarding the trigger. I have shot tens of thousands of rounds thru BSS guns and the only trigger issue I ever encountered was traced to some tinkering by an unqualified wannabe. He had intended to "slick up" the trigger by polishing on parts of it. The parts he polished rounded the corner of what I call the disconnector and allowed it to double. A simple mill file cut the corner sharp again and it hasn't missed a beat since. My opinion is that the BSS trigger is the best design I've encountered but it takes up a lot room in the works.
