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.

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

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

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.

, 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.
