The Chropi Rifle was a rifle type built by Chropei (which used the "Chropi" spelling on its weapons), a Greek chemical company. It was designed by a team under Mr. Sotiris Sofianopoulos (apparently based on an original Greek-Cypriot design) and was proposed to the Greek Army in 1975. It was a simple and rather outdated design, clearly inferior to the Heckler & Koch G3, which was adopted (produced by the state-run, Elliniki Biomihania Oplon company). The rifle was rejected after a series of tests indicated that the weapon itself did not adhere to all of the desired standards. The company, nonetheless, had created all necessary infrastructure for its production and a small number (probably a few dozen) produced was delivered to the Greek state and ended up in Greek Army storage facilities.
