Adam picks up a NERF Rival Nemesis blaster, and upgrades it with a custom magazine to hold a THOUSAND soft plastic NERF balls. Watch as Adam builds the new magazine from scratch, uses kit-bashing to detail the blaster, and adds more upgrades like the bi-pod and laser. And to test this massive rig, Adam sets his sights on some prehistoric prey! Life finds a way!
