Watch in 1st person as we dump a magazine of 5.56x45mm through an AR-15 pistol with our 3d-printed inconel muzzle brake, the NERO 556. Our custom GoPro mount looks right through an EOTech EXPS 3-0 as we rapid fire on our semi-auto AR pistol with a 10.5in barrel. Note the stability during rapid fire.
