A1 SIGHTS - DIFFERENCES & ADJUSTMENTS (continued)…
NOTE: To zero the rifle, adjust the front sight (elevation) and the rear sight (windage) so that you
can hit the aiming point at a given range.
FRONT SIGHT - To adjust elevation, depress detent and rotate post as
described previously for A2 Front Sight Post. The 5 notches of the A1 post
allow for a finer adjustment than does the square A2 Post with 4 notches.
NOTE: Bushmaster uses only the newer A2 square front sight post.
REAR SIGHT - To adjust windage, depress detent and rotate drum to
direction you want. Each notch moves the point of impact of bullet as
indicated in chart.
1.) To move point of impact to right, turn drum clockwise in direction
of arrow and letter R.
2.) To move point of impact to left, turn drum counterclockwise.

OPERATION OF YOUR RIFLE…
LOADING…
CAUTION:
ALWAYS POINT THE MUZZLE
IN A SAFE DIRECTION!
1.) With Hammer cocked,
place Selector Lever on SAFE.
2.) Open Bolt and check Chamber.
Make sure it is clear.
WARNING: If a noticeable difference in sound or recoil is experienced, STOP FIRING.
Either condition could indicate an incomplete powder burn and/or a bullet stuck in the
bore (Also see Page 45). Retract the bolt slowly and remove the fired cartridge case.
Clear the weapon and check for unburned powder grains in the receiver or bore, and for
a bullet stuck in the bore. Clean out any unburned powder before resuming firing. If a
bullet is stuck in the bore, do not attempt to remove it. Take the rifle to a qualified
gunsmith.
