So I'm getting problems I see alot of people are having semi works, but SS mode light strikes and dead trigger. I saw one video saying I may have to change my receiver to a low shelf one, but he did have a Ar9 dont know if 556 should have low shelf too. I have upgraded the buffer and bolt carrier to H3 and full auto BCG in my 7.5 ar15 556. Any help will be much appreciated. By the way I do have the steel SS kit.
