The Bow-Mount Scope/ Barrel Video Mount attaches directly to your scope or barrel so you can mount a video recording device of your choice allowing you to self record your hunts and target sessions with your guns or crossbow. It expands to fit a scope up to and including 32 mm and will go as small as an inch tube. It can be mounted on the front eyepiece, back bell, or somewhere in the middle of your scope. If you are shooting open sites, you would attach the mount upside down on the bottom of your barrel. A Bow-Mount Smart Phone Clamp is included allowing you to use your smart phones video capabilities to take the video.
