This is a very nice all original Spanish 1916 Mauser carbine chambered in 7mm Mauser. Mechanically this carbine works as it should. I have personally fired it and it functions great.  Ejection was a little weak, but did work.  This carbine would make a great first milsurp for someone looking to get into the collecting game.  It functions, it looks well, and it needs a good cleaning.
