n Place a target at the desired distance from
W the shooting point which will clearly show
the impact of the bullet from a known
point of aim. For this purpose a regular
bullseye paper target is most suited.
II
Shoot three or four shots at the target from
a prone or sitting position using a rest
under the forearm (not the barrel) and
supporting the elbows to maintain the rifle
in the steadiest manner possible. Unsteadiness
in holding the rifle on target will have a
considerably greater effect on the results
than either rifle or cartridge.
Shoot carefully and deliberately, trying as
much as possible to align the sights exactly
the same way each time. It is also
advisable to shoot a first shot through the
barrel before the sighting shots if the
barrel is clean and oiled, as the
combustion of the oil may change the
ballistics of the bullet slightly.
II
If sight correction is required, the rear sight
or the telescopic sight must be adjusted
accordingly. Some BAR's are fitted with
open sights consisting of a hooded front
sight and a fully adjustable rear sight as
well as being drilled and tapped to accept
scope mounts. Other BAR's are drilled and
tapped only to accept mounts for

~ If vertical correction is desired, loosen the
..
vertical adjustment screw and slide the rear
sight assembly along the inclined ramp of
the sight base. Again calibration marks on
the sight will reference movement, and simi-
larly, each calibration mark represents
approximately 4 inches at 100 yards.
Just remember this simple rule in making
rear sight adjustments. Always move your
rear sight in the same direction you want
the point of bullet impact to move. If you
want the point of bullet impact to move to
the left, move the rear sight setting to the
left. If you want to raise the point of
impact, raise your rear sight setting.
n To adjust a telescopic sight on your BAR
... rifle, the same general procedure, outlined
above, may be followed to sight in the rifle,
except the adjustment of the telescopic
sight should be made according to the
instructions supplied by the maker of the
sighting instrument used.

To obtain the 200 yard zero preferred by
.. many experienced hunters on a 100
YARDS
RANGE refer to the table in Figure
6. Merely adjust the sights in the manner
prescribed above so that at the 100 yards
range, the center of impact of your bullet
group is located at the distance ABOVE
30
telescopic sights. To adjust the BAR's open
rear sight proceed as follows: Always
unload your rifle before making any
alignment to the sights.
a
If horizontal or windage correction is
desired, slightly loosen the screw
immediately in front of the rear sight
notch. (This windage screw is set in a
bright metal collar; the screw next to it is
the vertical adjustment screw. Refer to
Figure 7.) Slide the rear sight blade in the
.
direction you wish the bullet impact to
move. The base containing the rear sight
blade is precisely calibrated for referencing.
Each calibration mark represents
approximately 4 inches of movement of
the point of impact at 100 yards.

this is achieved, the bullet will strike the
point of aim at 200 yards within ordinary
limits of dispersion for such ammunition at
that distance.

The trigger mechanism has been adjusted at the
factory to provide a short crisp pull, yet one
consistent with safety. The trigger is a single
stage design with the weight of pull holding
closely to 4 pounds. It is recommended that no
attempt be made to change the weight of pull of
the trigger.
