The rear sight assembly is riveted onto the receiver cover and consist of a square notched rear tangent iron sight calibrated in increments from and includes a "point-blank range" battle zero setting corresponding to a zero. It is identical in design to the AKM and Mosin–Nagant, except that it is oriented backwards with the notch forward and the hinge behind. The iron sight line has a sight radius. Like the RPD rear sight, the PK rear sight also features full windage adjustment in the form of small dials on either side of the notch.
