Does anyone have any idea what the difference in the velocity would be between a 16" and an 18" bbl? Im reffering to 5.56 loads with heavier 62-77gr bullets fwiw.

Depends on ammo, but this is a good estimate.

Maybe not that high. Pics are from Molon. Keep in mind that the difference between 18 and 20 is not at much as 16 to 18.
