REPAIR
The nylon fabric (1) of the pack body may be restitched, darned and patched. The felt lining may be restitched and
plugged.
a. Restitching. Restitch loose or broken stitching on body of pack (2), muzzle butt (3), and lowering line pocket (4)
directly over old stitching using size 3 thread, 5 to 8 stitches per inch, and an HD sewing machine. Lock stitching at least
½ inch.
b. Darning. Darn a hole or tear in the pack fabric, rifle butt or muzzle pockets that does not exceed 1 inch in
length or diameter using size E thread and a darning machine. There is no limit to darns that may be applied, provided
they do not weaken or reduce the original strength of the fabric more than 10%. If damage is in the lined portion of the
container body and only the cotton duck is damaged, darn through duck and felt. If felt is also damaged, remove
damaged area before darning duck fabric. Then plug felt as in c.(3) below.
c. Patching. There is no limit to the number of times the container body may be patched. Patch a hole or tear
that exceeds 1 inch in length or diameter following procedures in (1) or (2) below. Use nylon or cotton duck cloth
according to original construction for patching outside, and 1/4 inch thick felt for plugging inside lining. Use an HD
sewing machine, size 3 thread, and 5 to 8 stitches per inch.
