I think I saw your rifle at Wallmart, and it was Chinese made, if I am correct. I have used RWS guns in the past, not perfect, but they work, and the scope mounting system is very heavy duty.
I once had an RWS model 34, lots of people like them, but I found that the one I owned had a wondering zero problem with the open sights. I could not trust it as the thing would hit things to the side of what I was aiming at, too risky around a porch window, sold it. My RWS 52 with the fixed barrel was rock solid, aimed great, but it is not cheap to buy, and it is heavy to lift.
I guess I would look at what feels the best for you. Is there anyway you can sight the rifle without the scope to see if it is the gun?
