What's it's FPS like ?
What's it's accuracy like ?
If the answer to both questions is positive, IE an FPS of 330+ & your hitting what you point it at, then leave it alone, use your available funds to sort out another primary, maybe a short rifle so you've got a viable alternative for different roles, as well as being a valuable backup.
As for the sr25, if it's doing what's expected of it reasonably well, then leave it,if it ain't broke don't fix it, you might do more harm than good & inevitably create a money pit, something no one needs lol.
