After testing this on my ATV I removed it.  First the foam lining is thin but will still snag on your gun (I even tried gluing it inside the case using foam pads to compress the lining which worked until the first time a gun site snagged and then it was a mess getting it free). Second, there is LOTS of case vibration even with the Kolpin mount (too much to risk ruining my scope zero or risk damage to the scope).  I just carry my rifle slung over my shoulder and a cross my chest while riding.
