The Swamp Sniper shows the Brain Exploder Runcam 2 to use in creating scope cam footage... "How to sniper scope cam [ Brainexploder Runcam 2] with the Swamp Sniper airsoft gameplay. This is, in my opinion, the best way to scope cam using the Runcam 2 with 90mm lens from brain exploder. I also have a 35mm one for closer quarters. It's been a blast making scope cam footage with my M27, G28, Vsr-10, sos a1, Novritsch SSg24 and other sniper rifles.
