The AM simply has All Metal parts instead of the composite ones (gripframe, eye covers and feedneck). Everything else is the same as the LT, even the board.
You can buy an Emortal upgrade board for the AM that gives you an LCD screen.
I would have it myself but it'd have to be like 150 a month as im on a apprenticeships wage, which isnt much and i still have to make the rest of my money last.
So, its up to you mate, sell it to me for two payments of 150, or wait for someelse?
