Late in the show, "stock" or "other" footage from a previous episode was used when Adam shot one of Slayden's men (Mike) off the top of a big rock. There is also a "continuity" issue... the stunt man was not wearing the same clothes and hat as Mike before he climbed up the big rock.
Lastly, when the stunt man "hit the ground" below, the hidden "air bag" bounced up.
