Marlin makes a shorter stock compact version of the xs7
At 5`2" you would want the shorter butt stock to better fit your arm length. I would recommend either the 7mm-08 or 308win in the XS7 over the choices in the XL7 270, 30-06 etc. This rifle only weight 6.5 lbs and that makes it easy to carry even with one weak arm. It will have more felt recoil in the long action cartridges. I have only seen one of the rifles in the camo stock finish and I liked it. It may show scratches more with the camo finish.
