Nice rifle! Since I don't keep up with these rifles, what is a Lipsey Special?
Lipsey's made a special run of the Fieldcraft 6.5 CM with a 24" no.2 Douglas Contour, rather than the conventional 21" no.1 Douglas Contour... I prefer the slightly heavier, weight forward feel of the no.2 contour.
As 257 said, the no.2 is unthreaded, unlike the 21" which is threaded.
