El Dorado, AR: Desert Publications, 1982. Second printing. Wraps. 52, [2] pages. Illustrations. Blueprint Index. The Mini-14 is a lightweight semi-automatic rifle manufactured by Sturm, Ruger & Co. Introduced in 1973, it is based on the M14 rifle and is essentially a scaled-down version chambered in 5.56×45mm NATO. It is made in a number of variants, including: the Ranch Rifle (a basic, civilian variant), the Mini-14 GB, and the Mini Thirty, which is chambered for 7.62×39mm. The rifle is currently used by military personnel, law-enforcement personnel, and civilians in the United States and around the world. 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, 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. The original Mini-14 rifle had a rear aperture sight with large protective wings and no integral scope bases. In 1982, Ruger introduced the Ranch Rifle with an integral scope base on the receiver, a new folding-aperture rear sight, and factory scope rings. In 1987, Ruger introduced the Mini Thirty rifle chambered for the Russian 7.62×39mm cartridge. At the time, large quantities of surplus military ammunition were being imported into the United States at rock-bottom prices. Also, the 7.62×39mm is ballistically similar to the .30-30 Winchester cartridge. As a result, the Mini Thirty proved to be an effective deer rifle. In 2003, the design was overhauled to improve accuracy, update the styling, and reduce production costs. The standard Mini-14 was discontinued and the name became the family name for all Mini-14-type rifles. As of 2005, all Mini-14-type rifles are based on the Ranch Rifle design, with integral scope bases, a nonfolding ghost ring aperture rear sight, and a winged front sight similar to that used on the Ruger Police Carbine. They have serial numbers beginning with 580 and are sometimes referred to as 580-series Ranch Rifles. They also have a new modified gas system designed to reduce barrel vibration and can shoot two-inch groups at 100 yards, which is 2 minute of angle (MOA) accuracy. Around 2007 or 2008, Ruger added a heavier, larger-diameter barrel visibly tapered from gas block to muzzle. These changes combined with tighter tolerances result in greater potential accuracy. All Mini-14-type rifles are available in stainless steel or blued finish with hardwood, synthetic, or laminated stocks with 16.12-inch (409 mm) or 18.5-inch (470 mm) barrels. Condition: Very good / No dust jacket issued.
