Stone them smooth.
Make sure the buffer plug is at least
flush with the protrusion below the
plug. Try to turn the plug with your
finger. If the plug isn’t flush with the
protrusion, or if it turns, report it.
Look for dents in the buffer caused
by the op rod. If you spot any, the
buffer should be replaced.
Lock the buffer in place on the re-
ceiver and give it a tug. If the buffer’s
loose, report it to support.

rmorers, you know how worn
out shocks on your car cause all sorts
of damage because they can’t soften
the hard bumps of the road. Well, think
of what your M240 machine guns
suffer when their buffers have stopped

Rack Report
G
ood news, armorers! You no longer
have to get racks made for your ma-
chine guns. The Army now has one
rack that can handle the M2, MK 19,
M240, M249, and M60 machine guns.
Order the new rack with NSN 1095-
01-454-6320. You can also order an
M13 rack made just for the M249 with
NSN 1095-01-197-7902 or a rack only
for the MK 19 with NSN 1095-01-216-
9295.
If your unit can’t afford $900 for the
new rack, you can still have your sup-
port fabricate a rack for you. Plans for
constructing the rack are available from
your local ACALA logistics assistance
representative (LAR).
If you are on the Internet, you can
also find the plans on the Soldier Sup-
port Network at:
