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

", and the

heel approximately

• Shim 2 is neutral. This shim is already installed on

the rifle.

• Shim 3 lowers the comb approximately

", and the

heel approximately

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

". 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

", and

the heel approximately

" and will adjust the cast on

or cast off approximately

• 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

" and the heel approximately
