5. Move the studs to the left for cast on.
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 cheekpiece 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 screws. Be careful not to

over tighten.

9. Replace the cheekpiece onto the studs. If drop at

comb has already been set to your desired height,

tighten the two comb retaining screws securely.

If drop has not been set, leave the retaining screws loose

and proceed to “Adjusting Drop at Comb.”

Adjusting the drop at the comb allows you to align your

eye perfectly with the plane of the rib.
The drop measurement is determined by measuring the

distance between the plane formed by the top of the rib

and the top of the cheekpiece itself. The higher the

cheekpiece, the lower the drop. To set drop, perform

the following:
1. Loosen the two stock adjustment set screws on the

right side of the cheekpiece (if they were not left loose

after setting the cast) using a 3mm hex (Allen)

wrench. The cheekpiece will now move freely, up and

down on the stock adjustment studs.

2. Position the cheekpiece on the studs at the desired

drop up or down on the stock. Make sure the

adjustment on each stud is equal up and down. When

you have determined a possible setting, lightly tighten

the stock adjustment screws and then shoulder the

firearm to test the setting. Drop adjustments are a

matter of trial and error. Adjust a little at a time until

you obtain the desired sight picture on the rib.

Some shotguns are fitted with an adjustable stock that

allows you to make adjustments to the stock for cast and

drop. This feature is usually found on target models where

shooters benefit from highly customized settings.

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.

1. Using a 3mm Allen wrench, loosen the two comb

retaining screws on the right side of the removable

cheekpiece and remove the cheekpiece by lifting

upward (Figure 21). This exposes the cast on and cast

off adjustment mechanism. (The cheekpiece comes

set from the factory with cast in the center position.)

2. Loosen both the comb adjustment stud screws

located in the top of the stock adjustment studs

using the larger (3mm) Allen wrench that is provided

(Figure 22).

3. Slide each stud equally in the desired direction. Each

mark indicates 1⁄16" (Figure 23, page 31).

4. Move the studs to the right for cast off.
