b. With the gage remaining in the bore, hold weapon in a vertical position with end of barrel into
which gage was inserted pointing up. Ensure that if/when gage passes through barrel it will not be
damaged. Using hand pressure ONLY, flex portion of barrel between front sight assembly and
compensator in all four directions (left, right, forward, and back). If barrel is only slightly bent,
gage will drop through when barrel is flexed in one of these directions. Note the direction which
allowed the gage to drop through the barrel.
CAUTION
Remove the gage from the barrel before continuing.
NOTE
If the gage does not pass through the barrel when it is flexed, replace barrel
assembly.
c. Place barrel in a vise using appropriate protective jaws. Clamp barrel between front sight
assembly and compensator approximately 1 in. (2.54 cm) from front sight assembly. The barrel
assembly should be in a horizontal position with the side noted in step b toward repairman.
CAUTION
Do not apply pressure to the receiver.
d. Grasp the BARREL near the receiver so that when force is applied the barrel will flex in the same
direction as noted in step b.
e. Give barrel a sharp jerk of approximately 20 to 40 pounds of force.
f. Remove barrel from vise and recheck straightness (step a).
g. If gage still will not pass through barrel, perform step b to determine direction of bend. If barrel is
still bent in the same direction as before, perform steps c through f using slightly more force. If
barrel is now bent in the opposite direction, replace barrel assembly.
h. If gage passes freely through barrel, barrel shall be considered straight and continue in service.
i. If barrel has been straightened, the weapon must be targeted (WP 0015).
5. Replace all unserviceable parts as authorized by WP 0039.
