The FR 8 was used well into the 1970s by mounted Guardia Civil units in the Sierra Nevada Scout Rifle Influence Both rifles were modified to fire the 7.62×51mm NATO cartridge. The FR-8 was developed from the Model 1943 short rifle, which was based on "large ring" Model 1898 Mauser action. These three rifles are often referred to as being "small ring" Mausers, as the receiver ring is smaller in diameter than the latter Model 1898 by. The FR-7 was a modification of the Model 1916 short rifle, which in turn was based on the Mauser Model 1893. The rifles were made from existing stockpiles of Mauser bolt-action rifles. The FR7 and FR8 were introduced in the 1950s when the Spanish military was already implementing the CETME automatic rifle, but did not yet have sufficient inventory to equip and train all troops.
