Smooth hardwood stock, with vented synthetic upper cover, checkered pistol grip, and folding metal buttstock.

ADDITIONAL INTERNET INFORMATION

Who hasn’t looked at a Mini-14 or Mini-30 rifle and thought, man this baby would be a blast on full-auto? Well, it would seem great minds think alike because Sturm Ruger did just that back in the 1990s when they made a little-known variant built around this concept. The gun was the Ruger AC556, and it’s what is lovingly referred to in the full auto circles as a “buzzsaw”.
DESIGN
Ruger started work on the variant in 1978, specifically targeting government sales. In the back of his mind, Bill Ruger had always believed the Mini-14 could have competed as a valid military rifle (a sentiment shared by Colonel Jeff Cooper) if it just had the right features. Taking the standard Mini-14 layout as an example, with its CNC-made chrome-molybdenum steel barrel and breech and extensive use of music-wire coil springs, Ruger made a few changes.

First, the AC556 has a completely different receiver, not to mention the fire control group. The receivers had to be slightly longer to fit the select-fire mode switch at its rear part. This selector moves from regular semi-auto fire to 3-round burst, to full auto with a flick of the dial. It was located to the right-hand side of the rear sight, with all the way back being rock and roll. The gun still maintained its standard Mini-14/30 safety lever in the trigger guard. The fixed-piston gas system was beefed up a little, as it, in its time, was one of the few select-fire 5.56mm ‘rod’ guns on the market. The end of the barrel held a NATO standard flash hider that doubled as a grenade launcher for rifle grenades and recoil damper.

The gun was produced in two flavors for commandos looking for different things. The first gun, the standard AC-556, has a 7.3-pound empty weight (7.8 loaded with a 20-round mag) and was 38.75-inches overall with an 18.5-inch barrel.

The second was the AC-556K, a chopped-down version. Slightly heavier at 7.9-pounds loaded, it was much shorter at just 33.5-inches with its folding stock open, and right at 24 with it folded neatly out of the way. The fact that it had a 10-inch barrel helped a lot. These have also been referred to in some publications as AC-556F models (for folder). (THIS RIFLE)

Both guns had 1:10 rifling with six grooves and could fire at 700 rounds per minute. This meant you could empty a 30-round mag in the time it took to say, “That’s pretty doggone fast.”

GETTING ONE FOR YOUR OWN
Introduced in 1986, as the private sale of Class III full-auto firearms was being made illegal by the Hughes Amendment, the company marketed these guns only to police and military customers. As a ‘budget’ alternative to Colt-made M16 rifles, the gun caught on with some agencies and the company had enough sales to keep the line open for almost two decades. The fact that the gun wasn’t an "evil-looking black rifle" made it a good choice for departments with image issues or a finicky local government. It wasn’t until 1999 that the company pulled the plug on these neat little rippers.
