What's the difference in db readings compared to the factory EVOL moderator?
Hi Dana. I don't have a dedicated decibel meter to make a comparison. I guess I could download one of the decibel meter apps on my phone but I'm not so sure about the accuracy of them. What I do know is that the Gen1 Fatboy has a higher pitch than the factory moderator and that's with me behind the gun. I haven't had anyone else shoot it with me standing on the side to do a comparison yet.
The only reason I mentioned it, and you might not be aware is that the factory moderator is actually designed as part of the shroud system. If you look in the barrel nut you will see holes, the factory moderator acts as somewhat of a stripper and uses the volume of the entire shroud. I did some experimenting with several aftermarket moderators on my EVOL, most actually caused some accuracy issues. I realize some people like the oversized sniper rifle look but beyond cosmetic they do very little for gaining any type of performance.
In many cases I think it's a mental thing, it's larger so therefore it must be quieter. Personally I think so many moderators are ridiculously overpriced with very little innovation on internals other than changes to exterior cosmetics.
