This video explores the Spanish Mosqueton CB-51, a rare intermediate cartridge rifle prototype developed in the late 1940s and 1950s. Influenced by German designs like the StG-44, Spain experimented with self-loading rifles before adopting the CETME. The CB-51 features a Mauser-style stock with a long-stroke gas piston and rotating bolt action. Only 12 of these rifles were produced, alongside other concurrent CB-51 prototypes. The video also references related Spanish firearms like the FR-8 and CETME-L, as well as German designs like the MP-44 and Gerat 06/06H.
This video analyzes the Spanish FR-8 rifle, a modification of the M43 Mauser bolt-action rifle introduced in the 1950s. Developed as part of Spain's transition to the CETME semi-automatic rifle and the 7.62mm NATO cartridge, the FR-8 served as a training and second-line weapon. Key modifications include replacing the barrel with a 7.62mm version, altering the front sight to mimic the CETME, and incorporating a hollow tube below the barrel for cleaning kit storage. The rear sight was also updated to match CETME specifications. Notably, the FR-8 was designed for standard full-power 7.62 NATO ammunition, contrary to popular belief.
