i like my fullfield a lot. i'm not terribly gentle in the field, it's got more than one small dent, and it's performed well in spite. my only complaint is that if you get an unseasonably warm rain, or if you wear some kind of mask in the cold that directs your breath upwards, it doesn't always repel fogging well. that said, i'm not certain any scope does in those circumstances, it's just the only thing that's ever bothered me with it.
