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.” Shims marked 1R1L, 2R2L and
3R3L, will all adjust drop at comb the same amount as
shims 1, 2 and 3, and will also adjust the cast right or left
approximately 1 /
8
". You will notice that the two opposing
edges of these spacers are different in thickness. For right-
handed shooters, install shims between the receiver and
the stock with the R facing the end of the buttstock, so
its thicker side is on the left side. This casts the stock
slightly to the right, away from the face of a right-handed
shooter. If you turn the shim around so the L is facing the
end of the buttstock it will cast the stock to the left.
These shims with their respective stamps are further
clarified below:
• Shim 1R1L raises the comb approximately 1 / 16
", and
the heel approximately 1 /
8
" and will adjust the cast on
or cast off approximately 1 /
8
".
• Shim 2R2L adds the same amount of cast to the
stock as shim 1R1L with neutral drop like shim 2.
• Shim 3R3L adds the same amount of cast to the
stock as shims 1R1L and 2R2L, and lowers the comb
approximately 1 / 16
" and the heel approximately 1 / 8
".
