i need to know:how long is the stock (extended and non-extended)how wide is the stockand how thick is the stockthanks.
I believe it is pretty difficult to tell and searching the schematics of the crane stock will be as well. Best way is to check out your local gun range and the folks there that shoot guns with crane stocks installed. Also, though I am not too sure about this one, check if the crane stock is compatible for mil-spec buffer tubes and commercial spec buffer tubes. Otherwise, I am very much inaccurate in any of this response.
ever think of googling standart crane stock ?
