Referring now to FIG. 1, there is shown a gunstock 10,
a barrel 12, trigger 14, trigger guard 16 and a receiver
generally indicated at 18. This receiver is shown in
detail in the other ?gures and in general is cast in a
single piece with the frame, magazine ‘box 20, the trigger
mounting plates 22, etc. There are two plates 22 which
are mutually spaced to receive the trigger 14 therebetween
