Ruger Mini-14
semi-automatic rifle
The Mini-14 is a lightweight semi-automatic rifle manufactured by Sturm, Ruger & Co. Introduced in 1973, the design was outwardly similar to 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, corrections personnel, and civilians in the United States and around the world.
History and design
Introduced in 1973 by Sturm, Ruger & Co., the Mini-14 resembles a smaller version of the military M14 rifle. Designed by L. James Sullivan and William B. Ruger, it incorporated numerous innovations and cost-saving engineering changes. The Mini-14 rifle has an investment-cast, heat-treated receiver and is mechanically similar to the M1 rifle in the receiver area, but with a self-cleaning, fixed-piston gas system.
Initial rifles were produced with a complex, exposed-bolt hold-open device with no button for manual engagement. Stocks were somewhat angular, and heat shields were made of wood. These rifles, with serial number prefixes before 181, were tooled and redesigned with a new stock, new bolt hold-open mechanism, and other small changes.
