KAC is a smart bunch, and optimized the ports for the ammunition people were generally shooting. Keep in mind, the gun was originally designed for full power/pressure military ammunition, not the normal 55gr blasting fodder many folks use.
The answer you seek is not necessarily to change the carrier, but to select your ammunition wisely and optimize the gas port diameter, gas tube length (intermediate as a constant in this case), etc. for that ammo. This may mean a different barrel.
