I opened the port in the barrel to improve function shooting cheap Russian 55 grain unsuppressed. The block's 3 positions are open, restricted and off. Open is for unsuppressed shooting of plinking loads, restricted is for hotter loads & suppressed & off is for subsonic. This guy will make them to your specs- not sure if Noveske will. Plus they cost much less.
