Not impossible to use GoPro style on barrel mounts.
It is chunky, especially when the waterproof case is added for impact/paint sealing, but when you factor in a hopper on top or your hand below then it won't overly increase your target area
It can also be goggle mounted but, again quite chunky and this is likely to provide a target.
At A&D 1 I wore a GoPro clone helmet mounted above my head. But that game was in the dark, so no danger of being seen popping over bunkers. (As I had taped over the LEDs!)
I have been looking at front mounting on my goggles, but this has not yet been tested in an action situation and it gives me concerns about goggle straps holding as goggles are not meant to have a box hanging out in front of your mouth

I shall now direct over to my recent post on a thread on barrel cameras.
Note that contourscotland spotted my post and got in touch, but in the process put 2 & 2 together and realised who I am.n general on forums I am Tom, but if that's taken then I am Tommika.
Contourscotland are now sponsoring TFD, my post was after initial contact and prior to accepting us.
My advice still stands irrespective of the arrangement, I give my opinion in general and at the time had had assistance & advice for CS. He also ticks a number of boxes with me - buy British, buy from a paintballer, and a helpfull chap. He's also been around the forums I hang around and is a helpful chap.
On top of all that he chooses to live in Orkney, from which I originate, and you can't go wrong with tha

Contours tick all the boxes for paintball, they are compact, have many mounting options and are capable of surviving impact.
I haven't tested the impact on my GoPro clone, prefering to case it, the contour impact that I first saw also was not mine. It was messy, but no damage. I therefore have no worries about needing to case the contour. (Do check models about waterproof-ness though before playing or swimming then blaming me!)
