I have a fr-8 308 mauser i am trying to get the floor plate off. My other Mauser you just press drown the mag button and they come off. For the life of me it will not come off. The reason why i want to remove it i got a great deal on a 25 round trench mag. I have a trench mag on my other mauser a guy give me. He could not get to work in his mauser. It took me over a hour to fit it in my Mauser some filing and it works great. People at the range ask me if it semi auto. When i tell them its a bolt action they get a funny look on their face. A few ask me they would like to buy one because they said its neat looking a 25 round bolt action.
