The KAC 556 PRT silencers are an evolution of the legacy Inconel QDSS-NT4 design. The 556 QDC/CRS-PRT and QDC/MCQ-PRT represent the latest iteration of 5.56mm rifle silencers from KAC exhibiting high flow rate throughout the entire time regime. The silencers are DMLS manufactured and mount to host weapon systems using the KAC Quick Detach system; a simple and secure technology. The PRT series maintains much of the signature suppression performance of legacy KAC QDC and NT4 designs, while offering reduced operator hazard potential. This comprehensive research program examines the performance of both 556 PRT silencers mounted with multiple muzzle devices across multiple weapon systems.

In this study, the KAC QDC/CRS-PRT and QDC/MCQ-PRT performance metrics depend upon suppressing a supersonic centerfire rifle cartridge on several commonly fielded gas-operated rifle platforms with multiple muzzle devices, which is an incredibly difficult task. How would the KAC QDC/CRS-PRT and QDC/MCQ-PRT perform on your SR-15 or AR-15 with 3-Prong and MAMS mounts, and what tradeoffs are there, if any?
