It really depends on which one you have. By this I mean I have a 541t that has a bull barrell and came from the factory with a match chamber and has 2 reciever bolts. I have a friend that has one and his doesn't have the match chamber and only has 1 reciever bolt. My 541s doesn't have a match chamber but his does. I guess it depends on when they were manufactored. Long story short my 541t will out shoot my 541s but shoots about equal to my friends 541s
