History and design

Introduced in 1973 by Sturm, Ruger & Co., the Mini-14 resembles a smaller version of the military

. 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

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

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

(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 or barrels.

Variants

Ranch Rifle

The Ranch Rifle is a basic model offered in a wood or synthetic rifle stock paired with a blued or stainless steel receiver and a standard 18.5" tapered barrel (1:9" RH

). These rifles feature an adjustable ghost ring rear sight and winged front sight, and they are sold with a detachable Picatinny scope rail mount and a choice of two 20-round or 5-round detachable box magazines to comply with some U.S. states and other countries, which have laws restricting magazine capacity. All models are chambered in both .223 Remington and 5.56×45mm NATO ammunition except the Target Rifle variant (which is .223 only).

Target Rifle

Introduced in 2007, the "Target Rifle" version has a cold hammer-forged heavy barrel, adjustable harmonic tuner with adjustable MOA accuracy, and either a laminated wood or Hogue overmolded synthetic stock. The Target Rifle does not have iron sights but includes the standard scope rings and

The Mini Thirty is available with a 16.12" (Tactical Model) or 18.50" barrel having a twist rate of 1:10" RH, and is sold with two 20-round or 5-round box magazines. Ruger does not currently produce 30-round Mini Thirty magazines. The Mini Thirty shares many of the same design and accessory options with those of the smaller caliber Mini-14 Ranch Rifle.

Mini Thirty Tactical Rifle

The "Mini Thirty Tactical Rifle" variant was introduced in 2010. It closely mimics the Mini-14 Tactical Rifle variant, but in 7.62x39mm. It also has a shorter 16.12" barrel with flash suppressor, and is available with a standard fixed stock/fore end, or a collapsible ATI-brand stock with Picatinny rails.

Government models

Mini-14 GB

The Mini-14 GB ("government barrel") models feature either a pistol grip, side-folding stock, or a standard semipistol grip rifle stock, a 20- or 30-round magazine, bayonet lug, threaded barrel, and flash suppressor. Proof that GB stands for "government barrel" and not "government bayonet" can be seen in Ruger's new Tactical models and Ruger continuing to use "GB", which are catalogued for example KM-14/20GBCP. These models have no bayonet lug but do have the flash hider. Sales of the models with bayonet lug were intended only for law enforcement, military, and private security markets, and could only be found in Ruger's Law Enforcement Catalog. Many have entered the civilian market, though.

AC-556

Introduced in 1979, the AC-556 is a

version of the Mini-14 marketed for military and law-enforcement use. The design incorporates a selector on the right/rear of the receiver to select either semiautomatic, three-round burst, or full automatic fire modes; the manual safety at the front of the trigger guard operates the same as a standard Mini-14. The front sight is winged and incorporates a bayonet lug. The or barrel incorporates a flash suppressor, which can be used to launch approved tear-gas and smoke rifle grenades. A folding stock was used on the AC-556F and AC-556K. The rifle came equipped with 20-round magazines and a 30-round version was available for a time. The AC-556 was dropped from production in 1999 and Ruger stopped offering service for the rifle in 2009. By that time, some models became available for private civilian purchase in the NFA market.
