Balance point is right at the receiver/barrel junction, a little aft (obviously) with a magazine. I like it and the way it carries, but I suspect the 20" would be even better. I was more concerned about weight when I ordered the barrel. BTW, velocity with the 18" barrel and the "standard" 28.5gr 8206 123gr Amax load is 2440+/-, something else I can live with.
I guess I am at closer to 8 lbs with scope on top. That moves the center back a little. Good report on velocity! , and you got the 123gr over 2400fps. I got a chrono but didn't have it last time I was out fire forming 7.62x39. I used H335 and W748, mid loads to cycle the bolt yet no high pressure to damage things.
