Answer:
sergei gavrilovich simonov -lrb- russian : Сергей Гаврилович Симонов ; 9 april 1894 -- 6 may 1986 -rrb- was a russian weapons designer ; he is one of the fathers of the modern assault rifle .mostly known for the samozaryadnyi karabin sistemi simonova -lrb- russian : Самозарядный карабин системы Симонова -rrb- , 1945 -lrb- self-loading carbine , simonov 's system , 1945 -rrb- , or sks carbine , he also pioneered the assault and semi-automatic rifle field in the 1920s and 1930s , mostly under the supervision of both vladimir fyodorov and fedor tokarev .his early work preceded both the m1 garand -lrb- of 1933 -rrb- , and the later m1 carbine , ak-47 , and m16 series .born in 1894 in fedotov , simonov began work in a foundry immediately after completing his elementary school studies .by the end of world war i , after completing a basic technician 's course of instruction , he began working on a pioneering automatic rifle designed by vladimir grigoryevich fyodorov , the federov avtomat .after the russian revolution , simonov continued further at the moscow polytechnic institute , graduating in 1924 to work at russia 's giant tula arsenal .by 1926 he had become a quality-control inspector at tula , and by 1927 , had been promoted into the soviet design and development department where he worked directly under fyodorov .the simonov avs-36 , which entered service in the 1930s would see service in the early part of world war ii , up to about 1940 or so where it was replaced by other semi-automatic designs .during world war ii , simonov designed some firearms of his own ; a submachine gun which did not enter production , and a self-loading anti-tank rifle , the 14.5 x 114 mm ptrs , which went on to form the basis -- in scaled-down form - of the sks .an earlier semi-automatic rifle was hindered by official insistence on using the powerful 7.62 x 54 mm r , which was at that point standard amongst russian rifles ; unfortunately , as had been found the fedor tokarev 's svt-40 is a flawed design .the 7.62 x54r 's...
