Milspec Mojo emphasizes the importance of eliminating external variables for an accurate zero. He recommends using a rear bag for stability and a mag pod for an additional point of contact. He prefers zeroing at 100 yards for more accurate windage and elevation adjustments (make adjustments for airsoft). He demonstrates the process of adjusting the optic based on the bullet's impact on the target and he explains how to adjust the optic, noting that two clicks on the optic typically equal an inch of adjustment at 100 yards. He also covers zeroing a laser, advocating for a converging zero where the laser and bullet impact the same point at 100 yards. In the end, he concludes by reiterating the importance of a stable platform and an effective zero for rifle accuracy.
