he M249 machine gun has a new bipod, which means eventually you and your
support will need to order parts for it. It will be some time before the parts are added
to TM 9-1005-201-23&P, so keep these NSNs on hand for replacements.

Dear Editor,
On the previous page, you provide a list of the parts for the new M249
machine gun bipod. In my work as a TACOM LAR, I found that every armorer in
the brigade I support has had two problems with the new bipods:
• The spring pin (19) is being sheared off or is rounding the corners of the
bipod yoke (14). This lets the bipod legs spin freely under the weaon, striking
the soldier.
• The retaining ring (15) is coming off during normal use, allowing the entire
lower bipod assembly to come off the pivot post of the yoke.
Fortunately, Rock Island has fixed the problem with a new bipod design that
is welded around the yoke, which keeps the bipod legs from spinning and coming
off. NSN 1005-01-557-2453 brings a welded bipod yoke that replaces the
bipod yoke (14), retaining ring (15), bipod collar (16), and spring pin (19).
The new bipod yoke must be installed by field support.

he Army strives to provide Soldiers with the best lubricants possible for their weapons.
And as a result sometimes the lube manufacturers change.
That’s what is happening with CLP, the workhorse lube for most small arms. When you
order it, you may get CLP that comes in a bottle that looks nothing like what it’s come
in before. But this CLP is just as good or even better than the old CLP. Use it with total
conFdence. Of course, use up the CLP you have on hand before you order more.
Don’t depend on commercial websites for information on lubes. There are forms of CLP
out there that don’t meet Army performance standards.
If you ever have any questions about CLP or any lube used on small arms, contact your
local TACOM logistics assistance representative.
Let your -10 TM always be your guide on what to use to clean and lube your weapon.
