Noveske N4 Switchblock! I broke it... and then I fixed it?
This video details troubleshooting a Noveske N4 Switchblock that experienced significant malfunctions, including light strikes, extraction failures, and ejector issues, after approximately 800 rounds. The presenter found the Switchblock to be finicky with buffer systems and explored swapping components, including a Centurion bolt carrier. After returning to factory parts and cleaning, the rifle appeared to function correctly, though the exact cause of the initial problems remains somewhat unclear, potentially related to gas rings or component tolerances.
