The cylinder should come off very easy, but on new guns they do tend to put a drop of thread lock on the thread to stop movement, so sometimes you may need to heat the back end of the cylinder with a hair dryer to release the thread lock.
The cylinder just unscrews off anti clock wise.
Very easy job to do.
