Unless adjusting drop at comb, 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.
ADJUSTING DROP AT COMB
Adjusting the drop at the comb allows you to align your eye perfectly
with the plane of the rib. A correct sight picture for most shooters
should have you looking down the rib with the bottom of the front
bead resting on the top of the middle bead. This forms a “figure eight”
or “stacked” configuration. Some of the rib will be showing as you
sight down, but no rib will show between the beads. The important
thing is to line up correctly each time you shoot.
The Adjustable Comb has an height adjustment range of 11 increments,
at
1
16" per increment, resulting in approximately
5
8" of height
adjustment.
CAUTION: DO NOT GO BEYOND THE RANGE OF ADJUSTMENT
INCREMENTS. SHOULD THIS OCCUR, THE COMB WILL NOT BE PROPERLY
SECURED AND COULD RESULT IN DAMAGE TO THE FIREARM.
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:
BEFORE PERFORMING ANY ADJUSTMENTS, ALWAYS MAKE CERTAIN THERE IS
NO SHELL IN THE CHAMBER.

7
64" Allen
wrench through the hole found on the upper left of the recoil pad

This will sufficiently loosen the Adjustable Comb, allowing
adjustments to be easily made. The cheekpiece comes set from the
factory with comb in the lowest position.
GRACOIL MODEL: Remove the butt plate by inserting a
3
32" Allen
wrench into the single hole on the right side of the butt plate and
turn the set screw counterclockwise two turns to loosen the screw
(Figure 12). Removing the butt plate gives access to the the hole
found on the upper left of the stock plate. (Figure 13). Loosen the
