Wear plate for trunnion blocks

Abstract

An improved receiver assembly adapted for use in a weapon that fires cartridges fed into the same from an ammunition belt having metal links. The assembly includes a trunnion block having a surface and two oppositely disposed sides. The surface is delimited on two opposed sides thereof by retaining means formed along said edges of the trunnion block. A wear plate is adapted to removably overlie the surface, and absorbs contact from the metal links. The wear plate is planar, being made of hardened spring metal, preferably steel, type AlSl C 1045, hardened to R.sub.c 48-52. Two opposed edges of the wear plate have fastening means, preferably in the form of C-shaped flanges. These resiliently grip the retaining means to coact therewith in securing the wear plate to the trunnion block. A manually manipulatable tongue is formed on one of the flanges of the wear plate to facilitate placement and removal of the same. The retaining means on the trunnion block are flanges defined by one side of a channel, cut either in the block itself, or on a plate secured to the sides thereof.
