I have to lube the heck out of new auto's, be they rifles or shotguns.

You can stone or steel wool the rough spots down to help out the action but
that is a personal option, since some just think more ammo will finally smooth things out......
and it will.

Some don't like to mess with a high end weapon.........
but if just a stock weapon, I see no reason to not work on them.

I always check a rifles magazine and its feed ramp area for best results
as a minimal tune up.
