The Mauser Model 1871 adopted as the Gewehr 71 or Infanterie-Gewehr 71 ("I.G.Mod.71" was stamped on the rifles themselves) was the first rifle model in a distinguished line designed and manufactured by Paul Mauser and Wilhelm Mauser of the Mauser company and later mass-produced at Spandau.During 1870–71 trials with many different rifles took place, with the "M1869 Bavarian Werder" being the Mausers' chief competitor.
