If you want to use a guncam that looks like an AN/PEQ-16 box, here is one made by Rummbolt using an already popular action camera that airsofters use... "In case you watched some of my early videos, you maybe remember my self-built PEQ-Box-Scope Cam. Back in the days, I modded the meanwhile quite outdated RunCam 2 camera into an AN/PEQ-15 housing. But during the last months, it has became quite unrealiable, and rebuilding is not really possible because certain necessary parts are no longer availabe. So I decided to take a look into the current generation of scope cams and give you a detailed instruction on how you can turn them into a PEQ-Cam by yourself. Lets go!"
