The R4 is a South African assault rifle.

The R4 is also the second type of subway car ever to have run on the IND New York Subway. It was built by American Car & Foundry; between 1932 and 1933. It was practically identical to the R1 and the 500 R4s were numbered 400-899 to follow on from the R1's sequence of numbers.
