The Combat Application Technologies CACM 556 is a standard size 5.56 rifle silencer intended for high pressure applications. The combination of suppression performance and back pressure reduction of the CAT CACM 556 is currently unprecedented in the research. At a total length of 6.1-in with its included mount, the silencer provides hazard reduction that exceeds that of a significant amount of models on the current market, and even models that are significantly larger. The CACM implementation of SURGE BYPASS technology in the silencer demonstrates the further industry advancement in hybrid designs that continues to eclipse the performance of legacy systems. Though the silencer is intended for use on the dedicated CAT CACM 556 rifle platform, silencers using the CACM technology are slated to be available from the NANO muzzle device developer, Apparition Instruments, with model designation 5CM.

In this review, the CAT CACM 556 performance metrics depend upon suppressing a supersonic centerfire rifle cartridge on a short-barrel gas-operated rifle, which is an incredibly difficult task. How would the CAT CACM 556 or AI 5CM perform on your MK18 with a 10.3-in barrel?
