TARR Precision does a field test of two budget-friendly red dot optics purchased from Temu to see if they can survive more than a few minutes of actual use. He mounts a $20 "Fiachi" red dot on a 450 Bushmaster pistol and a $30 EOTech knockoff on a 12-gauge shotgun. After a baseline accuracy test at 12 yards, both setups are subjected to a durability stress test that involves repeatedly tossing the firearms onto the ground to see if the optics lose their zero or simply fall apart.
