.556 scope

The Mini-14 is a lightweight semi-automatic rifle manufactured by Sturm, Ruger & Co. Introduced in 1973, the design was outwardly based on the M14 rifle and is, in appearance, a scaled-down version chambered in 5.56×45mm NATO, though with its own gas system design.
Since 1973, Ruger has introduced several variants, including variants chambered in both .223 Remington and 5.56×45mm NATO, the Ranch Rifle with a civilian style rear aperture sight and integral scope ring mounts on the receiver, the Mini-14 GB with a bayonet lug and flash suppressor, variants with folding stocks, stainless steel versions of the most popular variants, a target version featuring a heavyweight barrel and barrel tuner, the Mini Thirty, which is chambered for 7.62×39mm, as well as variants chambered in 6.8mm Remington SPC and .300 AAC Blackout. The rifle is currently used by military personnel, law enforcement and corrections personnel, and civilians in the United States and around the world.
