comb by inserting a
7
⁄64" Allen wrench through the hole found on the
upper left of the stock plate and into the Allen screw located within
the stock plate (Figure 14). Turn wrench counterclockwise three full
turns to loosen Allen screw. This will sufficiently loosen the
Adjustable Comb, allowing adjustments to be easily made. The cheek-
piece comes set from the factory with comb in the lowest position.
2 With Allen screw loose, carefully adjust comb to desired position
(Figure 16) by sliding each post equally in the desired direction.
DROP AT COMB ADJUSTMENTS ARE A MATTER OF TRIAL
AND ERROR. Adjust in small increments until the desired sight
picture on the rib is reached. Each increment represents
1
⁄16".
3 To decrease drop at comb, carefully slide each post up equally. To
increase drop at comb, carefully slide each post down equally. Sliding
each post equally will reduce the chance of the comb binding.
4 STANDARD MODEL: Once your desired
drop at comb is obtained, tighten the
Allen screw in the recoil pad. The screw
needs to be firmly tightened, but be
careful not to over tighten. Drop is now
set on your shotgun.
GRACOIL MODEL: Once your desired
drop at comb is obtained, tighten the
Allen screw in the stock plate. The screw
needs to be firmly tightened, but be
careful not to over tighten. Drop is now
set on your shotgun.
Reinstall the butt plate by sliding it back into the stock and tighten
the set screws using the
3
⁄32" Allen wrench. Do not over tighten.
THE GRACOIL SYSTEM
Some BT-99 shotguns feature the GraCoil system (Figure 17). This
highly adjustable unit allows you to tailor the gun to suit your specific
fit requirements. The GraCoil system features an adjustable
compression unit to reduce recoil, adjustable length of pull and an
adjustable butt plate.
