The Lock-a-Draw is for compound bows.  It mounts on your bow sight, not on your bow. 
It will fit your bow if you have a bow sight with two threaded holes for mounting a bow mounted quiver.  If your bow sight does not have the holes for mounting a bow mounted quiver you will have to change your sight to one that supports a quiver to use the Lock-a-Draw.  If you already have a bow mounted quiver on your bow, you will have to remove the mounting block and install the quiver mounting block that comes with the Lock-a-Draw quiver.  If you have questions concerning this, please call me.  I stand behind my pledge to give refunds, but some people are returning their Lock-a-Draws saying it  doesn't fit their bow when it obviously does.  This results in extra costs for both the customer and myself.

Please be advised that the Lock-a-Draw requires simple assembly and tuning.  It comes with 31" rod that has to be cut off for your draw length , and the trigger release is glued on with epoxy cement.  Tuning involves bending the rod so that the string catch  matches your anchor  point when drawing the bow.  This is done by paper tuning.  Although the tuning instructions are enclosed with the Lock-a-Draw, they are available on this web as well at Tuning Instructions.pdf.  The Compound Bow Rest & Holder also requires simple assembly.  Complete instructions are enclosed with each unit.  Please note that the Lock-a-Draw is not appropriate for bows that require more than 25 lbs to maintain a draw.  For example, a 70 lb bow with a 65% letoff would be 70(1-0.65)= 24.5 lbs.

Unless you only shoot sitting down, you should also order a FOOT STIRRUP to cock the bow from a standing position.
