Better swivel protects receiver.

YOU'VE GOT TO DO SOMETHING ABOUT this SLING SWIVEL.

ITS RUBBING Me RAW!

I CAN'T TAKE IT ANYMORE!

I'VE GOT JUST THE FIX ...

... THE NEW SLING SWIVEL ADAPTER!

The snap hooks on the M249 machine gun's sling lend to wear and even crack the upper receiver hole where they attach to Ihe 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 100501-529-8406, the rear sling mounting kit with NSN 100501-529-8408, and the quick-release swivel with NSN 100501-529-9309. You'll need two swivels for each M249.

If the M249 receiver still has the grommet assembly, install the front mounting sling assembly like this:

1. Place the stud (1) into the thick spacer (2).

2. Place and hold the lug (4) in the inside of the grommet lip end first.

3. Add one drop of blue Loctite[R] 246, NSN 8030-01-499-3589, to the threads of the lug.

4. Screw the stud with spacer into the lug and snug down the stud.

If the receiver is missing the grommet assembly, install the sling like ihis:

1. Place the stud (1) into the thick spacer (2).

2. Place replacement grommet (3), lip end first, into the inside of the receiver where the missing grommet would normally be found.

3. Place and hold the lug (4), lip end first, in the inside of the receiver and into the spacer (2). The spacer can be on either the inside or outside of the receiver.

4. Add one drop of blue Locktite[R] 246 to the threads of the stud (1). Screw the stud with spacer (2) into the lug (4) and snug down the stud.

To install the rear mounting sling assembly:

1. Place the lug (6) through the hole in the buttplate eyelet.

2. Install the stud lug (7) on the opposite side of the buttplate eyelet.

3. Apply one drop of Locktite[R] to the threads of the cap screw (8).

4. Attach the lug to the stud lug by screwing the cap screw through the lug and into the stud lug. Snug down the cap screw.

To attach the quick-release swivel to the stud lugs:

1. Turn the thumb screw counterclockwise all the way out.

2. Push in on the thumb screw and turn the pivot plate to expose the sling swivel post.

3. Attach the sling swivel post to the lug or stud lug.

4. Push in on the thumb screw and turn the pivot plate up and onto the sling swivel post. The thumb screw will spin on the shaft and won't lock down.

5. Screw the thumb screw clockwise all the way down to hold the sling swivel in place.
