If it is shooting good currently with no fliers, then I'd leave it be. The 3 main things that I will do to a factory rifle are:

1) Free float the barrel
2) Lighten up the trigger
3) Bed it, only if it's needed.

When I first got into long range shooting I was running an inexpensive $500 Howa 1500 in 270 Winchester. The barrel was touching the stock at the end of the forend. When I free floated it, the action in the stock was such that it dropped the front of the barrel down more into the stock channel. So we bedded it to have a good base and keep the barrel free floated. We lightened up the trigger as well. The rifle went from shooting ok with some fliers once the barrel got warm, to 3/4 moa all day long out to 800 yards and much more consistent from shot to shot.

But not all factory rifles need this work. Bergara makes a very good factory rifle. The top 2 factory rifles that I recommend are the Tikka and Bergara rifles. Both shoot very well out of the box.

Damn, I ate a can of soup that’s been in my locker for two years.
