The R9 is one sweet rifle. It's very accurate, and it is very tight in construction--no bad tolerances, etc. The only thing that could stand some improvement is it has a little spring twang. It's not bad, and as long as it keeps shooting accurately, I have no intentions to change anything with a tune immediately. Maybe some day I'll tune it, but since it shoots so nice now, I'm in no hurry.
The firing cycle is very nice. Very quiet. No spring torque. The recoil isn't very bad, either. Like I said, it has a little spring vibration, but not all that bad. It's a great gun and I doubt I'll ever sell it.
