The replacement limbs for the compact folding survival bow are made from the best quality fiberglass produced in the USA. Made specifically for archery bow limbs, and made to last. 50 lb draw weight at 28 inches. The same great great and durable limbs as the 55 pound limbs for the folding bow, but at a draw weight that is easier to draw back. All limbs are interchangeable on the compact folding survival bow. About the only time you will need to take the bow down is to change out the limbs or reverse the limbs to convert it from right hand to left hand or vice versa. Price for one set of two limbs.
