Built this box blind on a trailer this fall. Blind is 4’x7’ with flip up plexiglass windows and light weight. Nice to have the option of moving it around the property.
Yes plenty of room to use a rifle. I have built a few stationary box blinds in 4x6 throughout the years and they have enough room to stretch your legs and good for gun or crossbow. Heater too!
One thing I did different this year was to keep the windows closed until I was ready to shoot. Kept my scent down and helped to deal with the thermals.
