Mauser still exists as an arms company, though I don't believe they market small arms.
Though a technicality, Mauser Waffen is not the same company as Mauser Werke, which ceased to exist at the end of WW2, then reincarnated later when sporting firearms became legal to own again (Mauser is currently owned by Rheinmetall). Yes, they make a beautiful rifle, although I am pretty sure I will not own one this year because they cost about as much as a small house. And they also make military arms. The MG3 is a fantastic light machinegun, basically the MG42 in 7.62X51mm NATO.
