The Mark II G is your base level Mark II with a wood stock. The more expensive Mark II will be a BV model which will have a little nicer stock and a heavy barrel. Will make the gun front heavy but more accurate. There is the FV-SR wich has a plastic stock but a threaded fluted heavy barrel. There are SS models which are great for all weather conditions. I think you be happy with your Mark II G for its lighter weight but still has a wood stock over the cheap plastic. Put a decent little scope on it and have fun. Hope this answers your question as I understood it.
