RUGER AR-556 FOR SALE
The Ruger AR-556 is a type of AR-15, the military-style rifle that has been used in many other mass shootings. The pistol version is essentially the same weapon as the rifle but with a shorter 10,5 inch barrel and an adjustable stabilizing brace on the back “to aid in accuracy, balance and recoil management”
“The AR-15 platform weapon – whether it’s in a long gun or pistol – essentially has the same firepower. It’s a semiautomatic made for combat,” said Timothy D. Lytton, a gun industry expert at Georgia State University.
“The AR-15 pistol is almost sort of a novelty. Essentially it’s the same firearm but with a much shorter barrel, and with a shorter stock, and it’s a smaller weapon. So the same way some people might want to drive a sports car because they like the feel of the compactness and the sort of speed, they take essentially a combat weapon or a combat-style weapon and they shrink it all down into sort of a miniature version.”
The AR-15 was designed for the U.S. military in the 1950s. It was invented by Eugene Stoner, who worked for a company called Armalite, which is where the AR originated. The number 556 refers to the caliber 5,56 millimeters
The Ruger AR-556 Pistol has a 10.5-inch barrel that is cold hammer-forged of 4140 chrome-moly.
The 9-inch, free-floated, hand guard offers MLOK on the sides and bottom, with a traditional Picatinny rail running down the top.
The gas system is direct impingement and takes advantage of the entire length of the hand guard as a “carbine-length”
The upper enjoys traditional features like a brass deflector and a forward assist, as well as a dust cover. The configuration is slick top and has no BUIS.
It does come with a 30-round Magpul PMAG and also has an SB Tactical, SBA3 Brace on the end that can be adjusted to various positions for different lengths of pull.
All the controls are normal AR-15 standard (not ambidextrous), though the grip appears to be unique to Ruger.
The trigger feels mil-spec and is all business, coming in at 7 pounds, 2.3 ounces on my Lyman Digital Scale
However, it is solid and only pulls back about 1.5mm before breaking. Reset is tactile and audible. There is also a slightly bowed trigger guard to accommodate a gloved trigger-finger
