have you looking directly down the center of the rib with
the front and middle beads in alignment.
You will notice that the two opposing edges of spacers
marked 1R 1L, 2R 2L, and 3R 3L differ in thickness. In
addition to adjusting the cast on/off to the right or left
0.1" per spacer (approximately
1 ⁄
8
"), spacers marked 1R 1L,
2R 2L, and 3R 3L, will also adjust the drop at comb and
heel the same amount as spacers 1, 2, and 3. Cast on/off
spacers, with their respective stamps are further clarified
here:
1RL This spacer raises the comb approximately 1 ⁄
16
" and
the heel approximately 1 ⁄
8
" and will also adjust the
cast on or off approximately 1 ⁄
8
". For right-handed
shooters, install this spacer with the R facing out,
toward the end of the buttstock, so its thicker side is
on the left side of the receiver. This casts the stock
slightly to the right, away from the face of a right-
handed shooter. Turn the spacer around so the L is
facing out and it will cast the stock to the left.
2RL This spacer adds 1 ⁄
8
" cast to the stock and the same
amount of drop (1 1 ⁄
2
") to the comb as spacer No. 2
(neutral spacer).
3RL This spacer adds 1 ⁄
8
" of cast to the stock and lowers the
comb approximately 1 ⁄
16
" and heel approximately 1 ⁄
8
".
