The slightly longer and heavier bolt carrier group has an additional lug at the rear of the bolt carrier group. On a full-auto AR-15 or M16, this rear lug pushes the sear release downwards which allows full auto (or burst) fire. In a semi-automatic rifle, this has zero effect on how the gun functions.
