New Hero 7 Go Pro What do I do with it?

Nice, congrats on the cool gift!

Action cams will have all sorts of 'accessories' as far as keeping them mounted, impact / water resistant, etc
The bottom of the cam will have a 1/4-20 threaded boss, so that you can mount it using standard 1/4-20 hardware.
[that's what most light-duty tripods use, as well as other mounting options]

There are cases for these [model specific] as well as different bases that will let you mount them to different things..

Since you asked - *Scope Mount* A few ways to do that would be to use a single scope ring [your scope's diameter]
Remove the base, and mount a flat plate to it, then mount a 3m sticky cam mount to that.
Those cam mounts are 2-pc. 1 installs on the cam, 1 installs on 'whatever'. Then the 2 pieces click or bolt together.
You could also use a *Handlebar* or *Seatpost* mount - as they can fit 25mm 1", or larger diameters..

That would allow your cam to mount on top of on the sides of the scope - giving you full view [non obstructing]

Here's an aftermarket seatpost mount for example:

Just remember that with these actions cams, they usually have a very large field of view [super wide angle aka fisheye lens]
so they're best for filming POV [point of view] or FPV [1st person view]

I'm not sure the extent that the Hero 7 will 'zoom in' / crop in, but, you may be able to do that / add to that in editing / post processing..

I've had handfuls of different action cams over the years [usually mounted on my RC multirotor aircraft to do aerial shots]
Sky is no longer the limit. haha

Good luck, and have fun with that thing!

Buckeye,

You're welcome!
And yeah, always try to think outside of the box first..
I learned that as a kid from MacGyver!

Sam -

If you have a picatinny rail anywhere on the gun you can go to ebay and search "camera picatinny mount". You can also buy picatinny to dovetail inserts if needed. Both are very inexpensive.

Scott, stop by this week, I have a new roll of Duct tape, should hold it securely.
