You say it feels lighter but is heavier.Picked it up today and unboxed. First impression was "is this a CZ? As some reviews state, at first it feels kind of cheap. This is probably due to the weight which is 6.6 lbs per the specs. Oddly this is heavier than the 527 Youth Carbine at 5.87 lbs but it feel lighter. The magazine is different as well - a plastic affair with the locking notch a shallow square on the front. I assume the piece which locks into this notch is metal, I did not check but will later. It takes a little pressure to lock in the mag, like there is a bit of a gasket. I wonder how durable this is and will probably do most reloading from the open action. You can reload the mag that way.
I ordered a Diamondback 1.756-5x32mm with medium rings from AA Optics. I wanted to replicate the Burris 2-7x35mm I have on my 527 carbine but that model is discontinued. I plan to take both to the range to compare. It will sadly be a while as my May-June is very busy work wise. But I think it will make a good match up.
Maybe. The 600's poly stock is light and the heavier contour barrel certainly shifts the weight. I want to double check the weights of both. Also, I don't want to give the impression I am not happy with the 600. If it shoots well the lighter weight will be an asset. The trigger is single stage, not two stage as on the 527, but it is very crisp and light. It is adjustable via an external four position screw and comes from the factory set at #2.You say it feels lighter but is heavier.
Maybe it has better balance?
