Yupp, the back end of both cylinders has a "DIN" fitting. The advantage of the type without the gauge is that you can refill the cylinder without having to remove it from the gun. I made the change in the other direction, my S200T has got a cylinder with a quickfill connector on the front end. I know its good for 40 flat shots from full so I just count my pellets out in batches so I know when it's time for a refill (the gauge was never that accurate anyway.....).
