That is crazy, buy now for $600...for a 12 twist?!
My Krieger came in last November. $600 and 11 month wait time, but mine was for an odd tight twist .510 caliber. Gotta pay to play.
I'm not too versed on dimensions, is that barrel something special (besides length)?
Maybe extra for convenience, or he may be trying to recoup what he has in it?
Price one from Krieger and you will know the answer.
