The Mauser brothers are best known for their bolt action rifles and automatic pistols, but Paul Mauser worked on a semiauto military rifle as well. His design was a long-recoil action, and was not ultimately successful.
We have a bunch more images on display on the Mauser 1905/06 semiauto page of the Vault.
Very cool weapon, I would love to get the opportunity to put my hands on one some day,
Jack
Hey, anyone known why this wasn’t sucessful because it looks quite capable but I ain’t no firearms expert.
