The list is hard to ignor.
I am going to go with "ARmalite".
I guess nobody is buying Avtomat then?
Cei-Rigotti is the original brain storm behind the gas operation of the early semi-auto's. In these rifles, and in the Soviet copycats of the times, the gas operating system is below the bore, as in the M-1 Garand of the 1930s/1940s and later the M-14s of USA 1950s and early 1960s vintage.
Both Walther and Haenel redesigned these and moved the gas operating system to the top of the bore, in the StG 44, which was then copied by the Soviets for the AK-47 and by Stoner for the AR-15.
The disadvantage of the gas system being located above the bore is the need for a huge triangular front sight blade, and the parallax that results from such a large offset. But everyone has been living with it since it became popular.
Adolf Hitler is credited with coining "sturmgewehr" which Stoner is credited with translating "assault rifle" which was included in the literature for the AR-15's.
I guess ArmaLite and assault rifle are easy to confuse with each other.
