The weapon is a licensed variant of the Israeli IMI Galil assault rifle with several modifications; both the stock and magazine are now made of a high-strength polymer and the stock was lengthened, adapting the weapon for the average South African soldier. Other detailed differences include the R4's lack of a carry handle and a number of improvements made to its internal operating mechanism.
