I wouldn't use a fixed 6x for a woods/brush gun. I'd go for a wider field of view. If looking at a fixed power, go with a 2.5x or find an old Leupold 3x on ebay. The Weaver Classics have a fixed 2.5x and a 1-3 variable. The Leupold Ultralites would work, as would a Nikon 1.5-4.5. Any of the 2-7x32's would work good too. Also the Bushnelll Elite 2-7x32, my first choice in that power range.
