USA
In 1866 by Winchester and Henry firearms
Puma rifles are made in Brazil by Amadeo Rossi International and distributed in the USA by Legacy Sports, Inc.
US Military weapons, primarily rifles and pistols were built under contract by several different kinds of companies. For example Singer sewing machine company made some Model 1911 .45 automatic pistols; Colt made some; Ivor Johnson may have made some; etc. M-14 Rifles sent off to the Vietnam War in the 1960's were often made by Harrington & Richardson, Remington, or Winchester, to name a few. If any Springfield model 1903 bolt action rifles have "Springfield" stamped on them then they are more valued than a Springfield rifle with "Remington" stamped on it. If a Winchester model 92 has "Winchester" stamped on it, it'll be far more valuable to a collector than a Winchester model 1892 with an Italian companies name stamped on it (Italy makes the most copies of US cowboy firearms). A word of caution: Today's HENRY repeating rifles which are MADE IN THE USA uses a marketing ploy, "inferring" in it's advertisement that it is the original HENRY RIFLE of American History. It will have HENRY stamped upon it; be advised those are NOT original Henry rifles; they are from a company named HENRY that was created in about 1992 in New York.
US Army long arms (rifles/muskets) were Made In The USA. Confederate States of America (CSA) long arms were primarily IMPORTED (from England/France).
Mossberg made all their rifles in the USA.
These excellent rifles are made in Turkey.

Almost every country makes rifles
Smith and Wesson does not build rifles. The rifles they sell are made for them.
I believe that current made rifles are made in the state of Maine.
