One of the most popular accessories for today's AR15 owner is a muzzle device. Want less muzzle flash? There's a device for that. Want less recoil? There's a device for that, too. Want less muzzle flash AND less recoil? Some devices even claim to perform multiple functions.
I have been closely studying how various muzzle devices perform for years, and this summer, with the assistance of Advanced Armament Company, B.E. Meyers, and Silencerco, was able to test a significant number of devices currently on the market in unique and highly educational ways. I did not manage to test all of the devices on the market, or even all of the most popular ones. I did include a good sample of different types of devices. It is my hope that after reviewing this article, the reader will be able to look at any muzzle device and be able to make an educated guess regarding its characteristics in a number of areas. As you will see, some perform quite similarly to one another.
