Heckler & Koch G3
The G3 was developed in the 1950s by German armament manufacturer Heckler & Koch GmbH (H&K) in collaboration with the Spanish state-owned design and development agency CETME. It was designed based off research by Mauser engineers towards the end of World War II. The rifle uses the roller-locked delay blowback system originally intended for the STG45 rifle that was to replace the STG44 rifle in the German military. The name "G3" stands for Gewehr 3 in which means Rifle 3 in German.
