I would like to suggest tuning it yourself. While sending out to be tuned and getting it back as a tack-driver is great, I have heard nothing but good things online from people having it done for them but doing it yourself is much more rewarding. There are many how to videos online and the work is not that mechanically demanding. Vortek is a good start for springs and there are other companies that have parts that can make the rifle quieter, vibration reduced, and more accurate. I have always found doing my own work on rifles enjoyable and gives me a better understanding of how to shoot them.
