In any case, test your rifle with your new configuration and see where it shoots and adjust your sights accordingly.
In a recent article published in a French hunting magazine, there was a test on a rifle regarding the shift of impacts with and without suppressors. The rifle was a new Sako 85 in 308. All the impacts with the different suppressors tested were upward from the initial group shot without suppressors. Ammunitions were Browning ammo. It is not a common thing to have the impacts shifting up, most of the time it is down, but I guess that particular rifle had a mind of its own.
In every cases the groups improved more or less with the different suppressors on. And remember that a suppressor can influence the shooter in a positive way on how he will handle the recoil and the blast and how he will press the trigger.
