Nylon V3 Tappet Plate. Can be used on M4/AR and other V2 gearboxes.
The SHS design features a slight angle on the part which attaches to the nozzle. This I'm told is to allow the nozzle to be pulled back further to help buckings with longer lips to feed better. If you're looking for a straight version we also sell the ZCI V3 Tappet plate.
