REPAIR OR REPLACEMENT - Continued
b. Cracks in the critical area at the front end of the buttstock are not acceptable and these buttstocks
must be replaced.
2. While buttplate is installed on rifle, inspect for cracks around the mounting holes. Check for cracks in
excess of 0.25 in. (0.64 cm) in length which extend through the buttplate. Replace if cracked.
3. Inspect door assembly for cracks, corrosion, stuck plunger, separations on outer face, or other damage.
Replace if defective.
4. Inspect buttstock for unauthorized markings. M16A2 buttstocks, PN 9349121, with unauthorized
markings may be used under the following conditions:
a. The only authorized markings are those which are temporary in nature, i.e., paint, tape, etc.
b. When marking a buttstock, only use temporary markings.
c. Buttstocks with unauthorized markings that have been stamped into the surface of the buttstock
will not be used.
d. Unauthorized markings that have previously been scratched, etched, carved, etc. may continue in
use if the marks do not extend into the fiber of the buttstock. Cutting into the fiber of the buttstock
may weaken it.
e. These marks may be at any location on the buttstock. Unauthorized markings are not desirable.
However, if previously applied, they will be allowed to continue in use due to the cost of the
buttstock.
5. Replace all unserviceable items as authorized by WP 0039.
