Griffin Armament EZ Brake, Optimus 9 Gen 2, and Optimus Micro on an AR15 20" Side-by-Side Comparison

I try to compare my Griffin Armament Optimus 9 and Optimus Micro on a 20" AR15 with different configurations. Honestly, I knew the microphones would be an issue. Without being able to truly measure the sound levels, the results where definitely not good from a production standpoint. The suppressors performed GREAT!!! I'm especially impressed with the micro. Here's a side by side comparison using three different microphones.
