Question

The Mini-14 was first introduced in 1973 by Sturm, Ruger & Co.

The name Mini-14 was coined because it 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 employs 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 and update the styling while at the same time reducing 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 now based on the Ranch Rifle design, with integral scope bases, a non-folding ghost ring aperture rear sight and a winged front sight similar to that used on the Ruger Police Carbine.

These upgraded rifles 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 vibratio and are capable of shooting 2 inch groups at 100 yards (2 minute of angle (MOA) accuracy).

Sometime between 2007 and 2008, Ruger added a heavier tapered barrel to the Mini series. The heavier barrel had an overall larger diameter with the barrel visibly becoming thicker in the final inches as the barrel approaches the gas block from the 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.✌️✌️✌️✌️✌️✌️✌️✌️✌️​
