Personally, I'd be taking it back to the guys that have my £2,300 and asking them why my brand new rifle is not performing as expected,I'm sure that if it's simply a transfer port switch, they would be happy to oblige.
Failing that, I'm sure Chris Cundey (chrisc) will be along to advise on and/or supply any and all the parts you require.
Enjoy the rifle.
P.S. How have you got a 2014 model rifle when it's still only 2013??
