I've been thinking about this and I was wondering how they work in detail . I know how to put a standard semi auto together to get full auto but really all your doing is letting the rifle slam fire . How does the M4/M16 have such a high rate of fire and not be slam firing . Is the bolt really locking up completely before the hammer is let go ? Is it some sort of timing thing that holds the hammer just a fraction of a second so it does not ride the BCG home ?
