I'm 6'4" and prefer a longer LOP as well. I thought about calling Wayne to see about getting an inch+ added but never got around to it. I had Mark Bansner add length to one of his stocks and respray and it was fairly reasonable. It will fit the masses.
Appreciate your info and feedback, I looked at some European websites to try and get info on the value of this particular Steyr. Further input from you on it's value would be appreciated as you have a bunch of them. I assume you collect the Steyr Luxus for a reason ---they are a finely built rifle.
