This is a review of the Gamma 556 muzzle brake by VG6. I’ve been running this muzzle brake on my rifle for a while now and did a review with it here on a full auto AR15 lower. While shooting in semi-auto, the rifle was completely flat with no muzzle rise or recoil…making for a very fast and accurate follow up shot. In full auto, however, there was actually a negative recoil effect forcing the muzzle down as I shot continuously. I was shooting American Eagle .223 in a 16″ barrel with a mid-length gas system. I got my Gamma 556 muzzle brake from www.pdsrifles.com. Thanks for watching! Don’t forget to like and share this video! Also you can keep up with us on facebook at www.facebook.com/walkerarmory
