A portable shooting rail for use with a tree stand includes a rear frame assembly for engaging a tree. The rear frame assembly has a pair of spaced rear arms for engaging a tree and a pair of spaced forward arms and a vertical support portion that extends upwardly from the arms for placement against the tree. The vertical support member has a bottom cross bar and a top cross bar. The forward arms extend outwardly from the vertical support portion such that an obtuse angle is formed between the forward arms. A pair of struts connects the top cross bar to the forward arms. The shooting rail also includes a rail structure that is detachably coupled to the rear frame, with the rail structure being formed of separate rail sections that attach to one another and to the rear frame assembly to define a completed loop.
