Just to start this section off by saying thankyou to John for putting up with my perseverance in trying to get this set up.
And welcome to everyone who has bought or is thinking about buying a Marlin 5Exi.
The idea of this section is to give some the benefit of their experience to others. Mark @ Marlin is still the best point of contact for technical points, but you might find sharing your problem on here will help others in the future.
I'll shut up waffling!
