Micah Mayfield and his guest try shooting with the Nemo Arms Omen Nitemare, a powerful gun chambered in .300 Winchester Magnum. They describe the firearm as ridiculous but also fun, noting its powerful muzzle brake which creates concussive shockwaves and gives the shooters a headache. The gun's recoil is surprisingly manageable, but it gets very hot after a single magazine and starts to have reliability issues after an estimated 150-200 rounds. They also test the gun by shooting at a riot helmet and propose a Nitemare test for suppressor companies to see which suppressor can withstand being shot to failure.
