The limbs mount on the back, limb wedges are different shape within limb. I suppose if one made a riser that had a cradle (limb bolt solid to it, the cradle doing the pivot). Not sure if the old Widows magnesium or aluminum.
I hunt with a 64 inch 50 lbs at 28 inches Bamabow. I've done it for about four years now. So far, I've killed two deer and four pigs with it. Those first couple years are a real learning curve when you hunt with a longbow.
