2021年6月5日 · Yes, a 53SD is possible. I built mine without any input from the experts because most were saying it couldn't be done. Good thing I didn't ask them because the one I built runs perfect. I used an RCM 53K barrel, a factory 53 bolt carrier and …

2010年8月26日 · A 53SD would serve a role in very specific purposes, ie. enrty weapon with capabilities of defeating soft body armor with operator hearing safety in mind. In a close quarter situation, there's minimal to no sonic crack because the round doesn't travel very far.
