Awesome on 14.5”+ barrels - Precision Armament AFAB Hybrid Muzzle Brake

This thing is amazing on my 14.5” and 16” barrels. It provides balanced performance in flash reduction, minimizing side concussion and braking. Be aware that the AFAB is not designed for sub 14.5” bbls in 5.56. I tried it on one of my 10.5” uppers but the pressures were just too high and it became very loud and blasty. No stars off for that because it’s clearly stated that this product isn’t designed for shorter bbls. Precision Armament’s other brake/FH in this category, the EFAB, IS designed for shorter bbls and does a fantastic job on all fronts. I love both the AFAB and EFAB. PA hit it out of the park.
