I have two 18" barrels for my Remington 870, both are factory barrels modified by Hans Vang (Vang Comp). Both have had their forcing cones back bored. One has vent ports along the top of the barrel, the other doesn't. There is no difference in muzzle lift between the barrel with the compensator vent ports and the barrel without.
