like charlesp said, the adl,bdl and cdl are options, along with bluing and floor plates.
no , there is no marking on the reciever or barrel that says cdl, or adl.
drop your barreled action on whatever stock you like, use a box mag, hinged floor or blind mag and enjoy your rifle.
dont get too hung up on the letter designators , if your rifle shoot nice groups your buddies can eat crow
