4. When you are satisfied with the
comb height, start the screws
through the pad and spacer(s)
into the holes in the stock.
5. Attach the comb to the stock
using the screwdriver. Turn the
screws clockwise to tighten. Do
not overtighten the screws.
17.3. ADJUSTING CAST AND DROP
AT COMB
Six shims are included with your
FNAR (Figure 12). The shims fit between the stock and receiver, allowing
customized adjustments to the comb and heel. Each shim is labeled/
stamped for a specific amount of adjustment. The neutral shim, No. 2, is
already installed on your rifle.
Drop at comb is defined as the place on the comb that your cheek rests
when taking aim. If drop at comb is correct, your eye naturally falls in line
with the sight. Shims marked 1, 2 and 3 do not give any cast on or off. The
stock remains straight. They only adjust drop at comb.
These shims with their respective stamps are further clarified here:
• Shim 1 raises the comb approximately
1
/
16", and the heel
approximately
1
/
8".
• Shim 2 is neutral. This shim is already installed on the rifle.
• Shim 3 lowers the comb approximately
1
/
16", and the heel
approximately
1
/
8".
Cast is the offset of the buttstock from the longitudinal center line of the
firearm. Some right-handed shooters like the stock to angle away (cast off)
from their face, making their line of sight more directly in line with the
barrel. Angling the stock to the left for left-handed shooters is “cast on.”
17.2. ADJUSTING COMB HEIGHT
Three combs have been included with your rifle to allow precise height
adjustments to allow correct eye-to-optics alignment (Figure 10). Three
combs are included with the FNAR, with 8mm height differences between
each comb. Comb #1 is the lowest comb, #2 is the middle height and #3
is the tallest comb. The #2 comb is installed on the rifle from the factory.
To install a comb perform the following operation:
1. Make sure your rifle is completely unloaded and the “safety” is in the
on safe position.
2. Use a #2 cross tip or Phillips screwdriver to remove the comb
(Figure 11). Place a small amount of petroleum jelly on the screw
access slits on the front and rear of the comb to prevent damaging
the comb. Insert the screwdriver into each of the two access holes.
Make certain the tip of the screwdriver engages the head of the screw.
Turn the screw counterclockwise until the screw is completely loose
from the stock. When both screws are free, remove the comb.
3. Install the new comb to fit the rifle to your specifications. After making
an adjustment hold the rifle to your shoulder to determine if the new
comb comfortably provides correct eye-to-optics alignment. Remember
to always keep the muzzle pointed in a safe direction, the safety in the
“on safe” position and make certain the rifle is completely unloaded.
