Optional Adjustable Comb_
This section applies only if your BT-100 is fitted with the optional, adjustable comb feature. Otherwise you may skip these instructions.
Adjustment of the comb allows you to achieve a perfect fit of the stock against your face. This is a crucial adjustment because it determines how correctly and consistently your eye will line up with the sight plane along the rib.
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 check 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".
