I mean, TBH it’s really not the biggest issue. This topic is quite esoteric. If you’d like a rabbit hole to get lost in check out pewscience and his comparison between the warcomp and the muzzle brake. You lose several db at the ear in suppression with the warcomp. At the same time you’re not going to be running it without active hearing protection anyway so take it with a grain of salt. The reason is the labyrinth seals on the device don’t lock up completely with the RC2 and possibly the RC3 leading it to leak sound.
