The parts to complete a custom WC-10 rifle lower receiver and the same parts they use in their shop for their custom WC-10 style rifles. This kit includes a right hand safety selector. As WC-10 style lowers have an integral trigger guard, no trigger guard or pin included. There are no fire control parts (Hammer, Trigger, Disconnector, Springs) included in this kit. Note-these parts are intended for use in a Wilson Combat WC-10 lower receiver only.
