im also wondering if the gasses from a muzzel break could also not be channeld into the rsb some how to reduce port size????? might also quite the gun some ntot sure the legalitys. a muzzel device desigend to cycle the gun might be cionsidered a supressor if it were to quiet the gun. then again if it part of the design to makle it work its not there to suppress. Im jsut thinking most guys but some sor tof zombie killing muzzel devive ont he gun. why not make it direct gas to help make it cycle?????? I looked at the idea ona accuracy build but never tried any thing.
