I have a Steyr HFT 2014 version since July this year. It is without doubt the best rifle I have ever had the pleasure to shoot. If fits me like a glove (Which in my opinion is very important)
There are official Steyr videos on You Tube that cover most technical/servicing that you might want to do by yourself.
Alternatively there are lots of very knowledgeable people on STB who can and will help out.
