Our WARRANTY is a 6 month no creep/serving separation warranty on BCY Trophy, X, 8190f, and Brownell Fury. If there are any issues I will quickly replace any affected string/cable. We try our best to avoid any mistakes, but if there are any I am happy to replace and/or fix the issue immediately. I just ask that you return the string/cable with the original receipt/packing slip for replacement. BCY Dynaflight 97/8125 el cheapo sets do not have a warranty.
