Question: The U.S. Repeating Arms Company is known for developing what kind of rifle action? 

Context paragraphs:
.45-60 Winchester: The .45-60 Winchester is a centerfire rifle cartridge intended for 19th-century big-game hunting.  Nomenclature of the era indicated the .45-60 cartridge contained a 0.45 in diameter bullet with 60 gr of black powder.  Winchester Repeating Arms Company shortened the .45-70 government cartridge to operate through the Winchester Model 1876 rifle's lever-action.  The Colt Lightning Carbine and the Whitney Arms Company's Kennedy lever-action rifle were also chambered for the .45-60.  These early rifles' advantage of faster loading for subsequent shots was soon eclipsed by the stronger and smoother Winchester Model 1886 action capable of handling longer cartridges including the popular full length .45-70.  The .45-60 and similarly short cartridges designed for the Model 1876 rifle faded into obsolescence as 20th-century hunters preferred more powerful smokeless powder loadings of cartridges designed for stronger rifles.  Winchester production of .45-60 cartridges ended during the great depression.

Volcanic Repeating Arms: The Volcanic Repeating Arms Company was a U.S. company formed in 1855 by partners Horace Smith and Daniel B. Wesson to develop Walter Hunt's Rocket Ball ammunition and lever action mechanism.  Volcanic made an improved version of the Rocket Ball ammunition, and a carbine and pistol version of the lever action gun to fire it.  While the Volcanic Repeating Arms Company was short lived, its descendants, Smith & Wesson and Winchester Repeating Arms Company, became major firearms manufacturers.

Winchester rifle: Winchester rifle is a comprehensive term describing a series of lever-action repeating rifles manufactured by the Winchester Repeating Arms Company.  Developed from the 1860 Henry rifle, Winchester rifles were among the earliest repeaters.  The Model 1873 was particularly successful, being colloquially known as "The Gun that Won the West".

List of Winchester models: Firearms produced by the Winchester Repeating Arms Company (later Winchester-Western Company and U.S. Repeating Arms Company), 1866–2006, by model:

Winchester Short Magnum: Winchester Short Magnum, or WSM, refers to a family of rebated rim bottlenecked centerfire short magnum cartridges developed in the early 2000s by the U.S. Repeating Arms Company, the maker of Winchester rifles and one of the oldest firearms manufacturers in the United States.  All of the WSM cartridges are based on the ".404 Jeffery" non-belted magnum cartridge which is shortened to fit a short rifle action (such as a .308 Winchester).

Winchester Magnum: Winchester Magnum refers to a "family" of cartridges developed by the Winchester Repeating Arms Company, one of the oldest firearms manufacturers in the United States, in the late 1950s and early 1960s, all based on the same basic cartridge case.  The basic case was a "short" magnum, meaning it would work through a standard (i.e.; .30-06) length rifle action rather than requiring the longer, magnum (i.e. .375 Holland & Holland) actions.

Herstal Group: Herstal Group is the parent company of small-arms brands manufacturing companies FN Herstal, U.S. Repeating Arms Company (Winchester) and Browning Arms Company.  It is based in Liège, Belgium, with offices in nine other European countries, North America and Asia.  It has a corporate partnership with Japanese company, Miroku Co.,Ltd..

Winchester Model 52: The Winchester Model 52 was a bolt-action .22-caliber target rifle introduced by the Winchester Repeating Arms Company in 1920.  For many years it was the premier smallbore match rifle in the United States, if not the world.  Known as the "King of the .22's," the Model 52 has been called by "Field & Stream" one of "the 50 best guns ever made" and by Winchester historian Herbert Houze "perfection in design."  However, by the 1970s the World War I-era design was showing its age and had given way in top-level competition to newer match rifles from Walther and Anschütz; the costly-to-produce Model 52, which had long been a loss leader prestige product by that time, was finally discontinued when US Repeating Arms took over the manufacture of Winchester rifles from Olin Corporation in 1980.

U.S. Repeating Arms Company: The U.S. Repeating Arms Company.  Inc. (USRAC) is the current business name of the Winchester Repeating Arms Company, famous for making Winchester rifles.

.300 Winchester Magnum: The .300 Winchester Magnum (also known as .300 Win Mag or 300WM) (7.62×67mm) is a belted, bottlenecked magnum rifle cartridge that was introduced by Winchester Repeating Arms Company in 1963.  The .300 Winchester Magnum is a magnum cartridge designed to fit in a standard rifle action.  It is based on the .375 H&H Magnum, which has been blown out, shortened, and necked down to accept a .30 caliber (7.62 mm) bullet.
