here are still a few snipers that haven’t had their XM107 sniper rifle converted to
an M107 by having MWO 9-1005-239-55-1 applied.
The MWO adds a new bolt carrier pin and a cheek pad, modiFes the charging
handle and moves the set bump.
How do you tell if you have an XM107 and not an M82 or M107 sniper rifle?
The XM107 has a full rail with a front sight that is not embedded in the rail. Most
XM107s have “XM107” stamped on the receiver, although this isn’t always true. If
the rifle’s serial number is lower than 7629, it’s an XM107. If the XM107 has been
modiFed, the “X” will be stamped out.
Dear Editor,
The safety slide on the MK 19 machine
gun can be installed backwards if you’re not
careful. Then the weapon can fire even when
it’s set to safety, which could be a disaster.
Armorers, before you let an MK 19 out
of the arms room, make sure the tab on the
safety slide is facing to the rear. That’s the
way it’s supposed to be.

Repair
If your XM107 or M107 ever needs repair, contact your TACOM LAR or the
TACOM-RI phone numbers and email listed previously. They will give you
instructions on how to send your rifle to the manufacturer for repair.
Editor’s note:
This is a good check to
add to your PMCS. Thanks for the tip.
If you have an XM107,
don’t try to send it to the manufacturer to have the
MWO done.
You will just waste your time and the manufacturer’s.
You must go
through TACOM-RI for the MWO.
That’s the only way.
If you have a local TACOM-RI logistics assistance representative (LAR), contact
him for help on what forms you need to Fll out and for shipping instructions for your
XM107. No LAR? Contact TACOM-Rock Island at DSN 793-0926, (309) 782-0926,
or email:
