Didn't see this covered in the threads. It appears Colt is producing a bolt action rifle. Chamberings offered in 308 win, and 6.5 creed. MSRP is $1899. From looking at the article. Seems all proprietary other than the chassis. Nothing mentioned about interchangeability. Doesn't seem like itd be worth $1899 when you can do a custom rig for a few hundred more.
