They ship from the factory bore sighted and with the scope. If you're looking at one w/o it, it has been removed for some reason.
I picked up a 770 .270, stainless and camo, new at wally world for about $250. It was a manufacture repair, some idiot at the counter had put the magazine in backwards and then beat on it until it went in. $10 part and 70% off once returned. Too cheap to not buy in todays market.
I bought dies, components, did up about 75 rounds and never fired it once. I decided the .270 was too much of an overlap in all my hunting rifles and I would end up using it just because I felt I had to. I ended up pulling the scope off of it and sold the rifle at auction for $650. I would do that again every day of the week
The scope lives on my loaner .243 now.
However I did a bunch of research after I bought it and found 2 definite reviews. 1 set by people that owned it and said it shot just fine, good for most hunters. The 2nd set by people that had never shot/owned one and said they were junk compared to the 700. A bit of an unfair bias IMO.
If you have no experience, don't complain.
Personally the biggest detraction would be the feel of the bolt. It does not use the same system that most are used to, and it ends up feeling very rough and sloppy when open. According to remy it does provide for a very secure lock once it's closed though.
With everything I've read and from owning it, I'd say that for the price it's a decent deal for a 1st time hunter or a sometimes shooter. Both of those would really be poorly served by spending 2-3 times the price for a 'good' rifle as they may never hunt again or actually take up shooting. I'd 2nd the 'backup' and 'loaner' position in the case for an active hunter/shooter.
