Own a FX Crown Mkll with two complete 600mm barrel assemblies.. One in .22 other.25 caliber. The Air Inlets on both barrels have a round port stamped “P” for pellets and a square/rectangular port stamped “S” for slugs. The barrels can be rotated 180 degrees. Question: If someone plans to shoot primarily pellets, should the round hole in the Inlet be positioned in an upward or downward direction? TIA
