For the most part yes. However, sometimes random parts need a little fitting. On mine, by far the worst was trying a Remington barrel on it. The DA receiver indexing was so bad the sights pointed to about 11:00.
I like the DA grizzly a lot for the money. However, my bottom line take on it; if you're going to mod the snot out of it buy a good old Wingmaster receiver and build from there. Cost ends up in the same ballpark anyway and with the WM you end up in a better place IMO.
I'll agree the first couple years of production seemed like fit/finish was lacking (but I think they've come a long way since then). To be fair though, it's not like the express hasn't had it's share of issues. I don't think every grizz/870 needs a complete tear down out of the box, but a couple cheap mods make them a whole lot more reliable and fun to shoot.
Your mileage may vary of course.
