21st Century Gunfighter LLC and United States Shooting Academy got together to take a look at muzzle devices. There are loads of them out there so it’s good to see someone take a look at them. They are right up front about stating that this isn’t a scientific test but that they have mitigated random influences as much as reasonably possible. All demos were preformed on the same day, with the same gun and the same ammunition, by the same shooters. This is a shooting evaluation so it’s subjective, but interesting.
We recommend you take a look at the entire series.
