Medi-Dart #6 Needle Valve Assembly is made where more grip is needed. This needle works well for doctoring yearlings or fall calves. The #6 needle must be paired with the new half moon push rod and the new wingnut. Assembly includes a #6 needle, half-moon push rod, and new wingnut, or just the wingnut and needle-no push rod. MDAKCBW or MDAKEW.
A new #6 needle is included with the Crossbow Kits, along with two wingnuts.
This assembly can be used with the previous crossbow kits to update to the new #6
