I ordered it yesterday morning and got it this afternoon. Opened the box and at first I had my doubts about fit and finish. After I got it out of the plastic liner I was very pleased with the finish on the barrel and stock. I took it outside on the patio and gave her a good look see. My impression is that this is a well made gun on the outside. Wood is good and blueing is excellent. The iron sites are superb as well. Shoved a Gamo Hunter .177 round nose down its throat and sat and looked for something to shoot at on the side of the property. Spotted a red coke can someone tossed next to the bushes. I normally do all my shooting from a bench but I was just sitting in a patio chair at the moment with a tin of Gamo pellets on the table. First shot hit right where I aimed for in the middle of the can. The can was approximately 30 yards or so out. Loaded up another, aimed and fired. Again I nailed the can somewhere in the middle of it. I continued through about twenty pellets and did not miss one.. lol At this point I am almost wetting my pants and had not put my Depends on this morning after my shower..

As far as accuracy it is excellent out of the box. Another thing surprised me was that there was no smoke from the breach or barrel which most other new air rifles have initially.
This gun cocks like cutting through butter. It does have a slight amount of twang and of course some spring noise. But not as bad as many new air rifles I have purchased. It has an odd safety on the underside of the barrel which you have to pull in order to cock it. There is a 1/4" round pin that comes out the back of the action which is the safety. The trigger is a bit mushy but not real hard to pull. That will be addressed in my next review after it has been completely tuned.
It seems to weight around 6 1/2 lbs. This CZ 634 will be a keeper for sure. I can't wait to scope it and check it out on some paper. Not to concerned about FPS because I will only use this one for targets. Now I am gonna hit the button tonight on the HW 50s and hope I get the same impression when it arrives...
