These bow sets are modified from NOS MilSpec bows. Cut in two places, they ship via standard UPS and FedEx, instead of truck freight charges. They are still an oversize package, but not truck freight. Carefully cut, these bow sets come with instructions, bow pieces, splices (4) and self-tapping screws to fasten the splices.
 
Pair them with MilSpec spreader bows (NOT INCLUDED) or MadMountain's 5-bar clamp on crossbars (NOT INCLUDED).
