CRS1100-052 Center Receiver Screw

Center Receiver Screw for Crosman Model 1100 CO2 Shotgun, and others.  The original was a self-tapping screw, the design of the self-tapping feature was later changed to better facilitate cutting the threads.   After production ended, there was no need for the self-tapping feature and Machine screws were used by the factory for repairs.   These will be shipped without regard to the thread feature depending on our stock.
