Exprest™ keeps it simple. It is the only tape mounted, twin arm rest to hold from the smallest carbon to the largest aluminum arrow with no gaps. Eliminates need to hold arrow by hand or the use of an arrow holder. Draws quietly and smoothly without skip. Arms fold down-and-away for a clean, accurate launch. Works on right and left handed bows and is great for bowfishing too. - Custom fit any shaft size - Holds arrow secure - Reversible right or left hand
