The JR-15 is a semi-automatic .22 cal. Similar to the Marlin I had as a teenager. However, I think the JR can be expanded to a larger magazine capacity than I had, I can’t remember if mine was 7 or 10 rounds.
That's not a toy gun. That's a fully-functional, miniaturized version of an assault rifle marketed as a "JR-15." Needless to say, these didn't exist back in the good ol' days. DEMOCRATS AREN'T THE ONES WHO HAVE LOST THEIR MINDS ON GUNS. REPUBLICANS ARE.
