NBC
NCOs, there are two pieces of equipment for the M40/M42 masks that will
help your customers see better and safer:
New Optical Inserts
The old one-piece optical insert has been replaced by an M40/M42 vision correc-
tion mount and a prescription lens carrier. When you have a soldier who needs a new
optical insert, first check with your local NBC supply office to see if they have any
vision correction mounts on hand. If they don't, let your optical lab know when you
order new lenses. They will usually provide the mount if you don't have any on-hand.
If your optical lab doesn't have any mounts or you need to replace a broken mount,
order one with NSN 4240-01-389-7152. Instructions for installing, removing, and
adjusting the new optical insert are on Page 2-68 of the M40A1/M42A2's TM 3-
4240-346-20&P.
For more info, see SBCCOM supply advisory message 03-07-002 or contact
SBCCOM's Doug Vanatta at DSN 793-3053/(309) 782-3053 or email:

M1 Laser Ballistic Outserts
The outserts protect soldiers' eyes from lasers and low-speed fragments and can be
used with both the M40 and M42 masks. They come with NSN 4240-01-434-1503.

M40-Series Masks…
Stopping L o o s e Harnesses
Dear Editor,
A loose M40 headharness could
keep the mask from protecting a
soldier. A harness too tight can
give a soldier a terrible headache.
We've found this procedure har-
nesses headharness problems:
Is the headharness tight enough
and does it have enough snap to
keep the mask tight? An easy way
to tell is to put a finger flat under
the cheek strap. If you can't get
your finger under the strap, it's
too tight and needs to be adjust-
ed. Turn your finger sideways and
quickly pull it out from under the
strap. If the strap snaps back in
place, it's strong enough. If it
doesn't, the headharness probably
needs to be replaced.
