Adjusting cast on and cast off allows you to achieve a perfect fit from the stock to your face. This is a most crucial adjustment, as it determines how correctly and consistently your eye will line up with the sight plane along the barrel rib. A shotgun correctly adjusted for cast on and cast off will have you looking directly down the center of the rib with the front and middle beads in alignment.
BEFORE PERFORMING ANY ADJUSTMENTS, ALWAYS MAKE CERTAIN THERE ARE NO SHELLS IN THE CHAMBERS AND THE SAFETY IS IN THE "ON SAFE" POSITION.
1. Loosen the two stock adjustment set screws on the right side of the removable cheek piece and remove the cheek piece by lifting upward (Figure 20).This

exposes the cast on and cast off adjustment mechanism. (The cheek piece comes set from the factory with cast in the center position.)
2. Loosen both the stock adjustment stud screws located in the top of the stock adjustment studs using the larger (3mm) Allen wrench that is provided (Figure 21). It only takes a fractional turn to loosen them adequately.
3. Slide each stud equally in the desired direction. Each mark indicates Viô".
4. Move the studs to the right for cast off (Figure 22A).
5. Move the studs to the left for cast on (Figure 22B).
6. Right-handed shooters may desire some cast off, with left-handed shooters preferring some cast on. The terminology is the same for right- or left-handed shooters. The net effect is to move the cheek piece to allow the face to move farther over the stock for better eye-to-rib alignment.
7. When properly set, the front and rear sight beads should line up perfectly each time you shoulder your shotgun.
8. Tighten the stock adjustment stud screws. Be careful not to over tighten.
9. Replace the cheek piece onto the studs. If drop at comb has already been set to your desired height, tighten the two stock adjustment set screws securely. If drop has not been set, leave the set screws loose and proceed to "Adjusting Drop at Comb."
