Neither of the hunting rifles shown have any sort of sights. When Delco and the tech are at the range you see the tech aiming the rifle, but there are no sights to aim with. There are however two piece scope mounts on the rifle, but they useless for aiming without a scope attached to them. If there were sights on the rifle, there would be a front sight on the end of the barrel, but as you can see there is nothing on the end of the barrel.
