Raven (PDI) Cylinder Full Set for ARES AW338 Series
AW338 cylinder seems to be same as VSR-10 size. But actually not same, we don't know that difference is that ARES intentional or not. PDI make new size because that difference will be affect the position when stop the bolt. So this cylinder is surely new size for specific to AW338.
