T
he snap hooks on the M249
machine gun’s sling tend to
wear and even crack the upper
receiver hole where they attach
to the receiver. If the receiver
hole is cracked, the receiver
has to be coded out. Good
news! The new sling swivel
adapter will stop that wear.
Order
the
front
sling
mounting kit with NSN 1005-
01-529-8406,
the
rear
sling
mounting kit with NSN 1005-
01-529-8408, and the quick-
release swivel with NSN 1005-
01-529-9309. You’ll need two
swivels for each M249.
