Sorry for the poor audio - I was filming in an indoor range with a loud ventilation system running. But it was a chance to shoot a proper select-fire SIG-Manurhin 540, and I wasn't going to let that opportunity get away! It's a quite nice rifle, weighing in at 3.5kg / 7.75 pounds in 5.56mm. Frankly, its handling and shooting was pretty comparable to other 5.56 assault rifles, like the FNC, AR-70, and AR-18.
