i beg your pardon, comb is adjustable for poi and sight alignment. cast is how it bends into your centerline cheek weld.
odds are your gun is a rh cast. its the most common. reason im asking is im a lefty. id be interested if its at least a zero cast.
if you look back at the butt over the receiver, you might be able to see it w/o assembling it all.
if youre willing, im willing to stay interested. thanks in advance.
C. To adjust the comb for CAST OFF or CAST ON, loosen the two Allen screws
on the right side of the comb and remove the comb from the buttstock.
Loosen the screw located inside the top of each of the posts. If cast off is
desired, move each of the posts to the right approximately the same amount
and retighten the screws. To get cast on, move the posts to the left. Re-install
the comb and check your sight picture. Readjust if necessary until all
adjustments put the pattern at the preferred location for the individual
shooter. Then tighten all adjustment screws securely.
To Raise or Lower the Height of the Buttstock
B. To adjust the COMB HEIGHT, loosen the two Allen clamp screws on the
