One of the farmers whose land I occasionally stalk on has asked me for help to control foxes. We went out the other night in his pickup, him driving, me kneeling in the back resting the rifle on a bipod on the roof of the cab. My problem was that, as I scanned left to right with the nightsight, I had to keep lifting the rifle and bipod off the roof and putting it back down, or try sliding it along which made a hell of a racket. I wondered if anyone had thoughts/ suggestions for a way to rest the rifle on something on the cab roof which would make it easier to move the rifle from side to side? Any advice/ suggestions gratefully received.
