"StG45 assault rifle "1945,Germany "7.92x33mm Kurz"(WW2)

"This was the last attempt for Germany to produce an assault rifle but cheaper and easier to produce/maintain etc. Like the previous and similar Sturmgewehr 44, It retained the same ammunition,ergonomics,magazines but instead used a roller-locking system that later became used in the CETME/Heckler & Koch series of weapons.
