Ruger Mini-14

The Mini-14, Mini Thirty, and Mini-6.8 are small, lightweight semi-automatic carbines manufactured by the U.S. firearms company Sturm, Ruger. The Mini-14 non-target versions can fire both the .223 Remington cartridge and the similar military 5.56x45mm cartridge. The target model Mini-14 rifles are chambered only for the .223 Remington cartridge. The Mini Thirty uses the 7.62×39mm and the Mini-6.8 fires 6.8 mm Remington SPC.

Ruger offered a selective fire variant of the Mini-14, the AC-556, to police and military customers. AC-556 models have a slightly longer receiver (shared with early production "series 180" models) to allow for full automatic operation. These models are available with features such as short barrels and bayonet lugs. The Mini-14GB model is a semi-automatic variant for police and military use with the additional factory options of a short barrel, folding paratrooper stock, flash suppressor and a bayonet lug
