Colt rifle with GoPro and Sportsman mount. The mount clips directly to the barrel, and on an AR-15 with a Government profile barrel and front sight gas block, will need to be clamped ahead of the M203 cut.

Behind the M203 cut, the mount may bump into the FSB. Several configurations are possible, however, and I did not get to try all of them.

The mount locks to the barrel with a fairly simply locking lever and screw. While this seemed satisfactory enough, the same system being used almost universally in locking down bicycle tires and seat posts, the clamp didn’t seem ideal for mounting to a firearm barrel.

The Hero3+ camera was not too heavy, and the plastic mount did not add much additional weight – but out at the end of the barrel, the difference was noticeable.

It remains to be seen whether the polymer construction would hold up well clamped directly to the barrel during extended shooting sessions. Further, I was unable to determine how the mount would affect the point of impact of the gun. Generally speaking, I would have preferred a Picatinny rail mount option.

All the accessories that came with the Sportsman mount. Hero3+ camera and transparent case not included. Worth noting, I had some difficulty figuring out how to mount the camera in the intended way, and ended up attaching the camera’s transparent stock mount directly to the sportsman clamp. The manual was not very helpful in this regard.
