About the Manufacturer:

THIS IS REMINGTON COUNTRY
For more than 200 years, Remington firearms have been forged from the untamed spirit that will always define our nation. The proud tradition that began with Eliphalet Remington's first hand-built rifle in 1816, continues to this day. Remington innovation is always ahead of its time, as evidenced by our rich history and long line of legendary firearms. The Model 700 and Model 870 have claimed their rightful places among the best-selling firearms of all time. Today, the Versa Max is quickly becoming the go-to firearm of choice for hardcore waterfowlers and the most demanding 3-gun competitors an American icon on the rise. And Remington handguns like the Model 1911 R1 and the R51 are reinventing shootability and redefining performance. At our state-of-the-art R&D facility the Rock we're shattering convention and setting the performance standard all others must follow. As new generations inherit the American sporting heritage, we continue to expand, building new plants and acquiring new companies to meet the challenge of increased demand. Revolutionizing an industry. Building a nation. Remington Country is, was and always will be bigger than any one place boundless as the American spirit.

About the .223 Remington Cartridge
The .223 Remington or .223 Rem is a cartridge with almost the same external dimensions as the 5.56x45mm NATO military cartridge. The name is commonly pronounced either two-two-three or two-twenty-three. It is loaded with a 0.224-inch(5.56 mm) diameter jacketed bullet, with weights ranging from 40 to 90 grains(2.6 to 5.8 g), though the most common loading by far is 55 grains (3.6 g).While the external case dimensions are very similar, the .223 Remington and 5.56x45mm differ in both maximum pressure and chamber shape. The maximum and mean pressures for some varieties of the 5.56 (different cartridge designations have different standards) exceed the SAAMI maximum for the .223 Remington, and the methods for measuring pressures differ between NATO and SAAMI. The 5.56 chamber specification has also changed since its adoption, as the current military loading (NATO SS-109 or US M855) uses longer, heavier bullets than the original loading. This has resulted in a lengthening of the throat in the 5.56 chamber. Thus, while .223 Remington ammunition can be safely fired in a rifle chambered for 5.56x45mm NATO, firing 5.56 ammunition in a .223 Remington chamber may produce pressures in excess of even the 5.56 specifications due to the shorter throat.
