"Bad pintle, better swivel"
PS Magazine, Dec 2007

---------------------

Do not use the M60 pintle to mount the M249 if you can avoid it. Even though WP 0009-00-1 in TM 9-1005-245-13&P, the machine gun mount TM, says that's OK, it's not preferred. The M60 pintle can damage the M249 receiver.

To mount the M249 on the MI22A1 tripod or the M197 mount, use the M249/ M240 machine gun pintle, NSN 1005-01-461-2656, and the rear adapter, NSN 100501-225-1156.

Use the new sling swivel adapters. The snap hooks on the sling tend to wear and even crack the upper receiver hole where the snap hooks attach to the receiver. The new sling swivel adapter will stop that wear. Order the front sling mounting kit with NSN 1005-01-529-8408, the rear sling mounting kit with NSN 1005-01-529-8406, and the quick-release swivel with NSN 1005-01-529-9309. You'll need two swivels.

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

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

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

3. Add one drop of blue Locktite 246. NSN 8030-01-499-3589, to the threads of the lug.

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

[ILLUSTRATION OMITTED]

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

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

2. Place the spacer (3) lip end first into the inside of the receiver where the grommet would normally be.

3. Place and hold the stud (4) lip end first in the inside of the receiver and into the spacer (3).

4. Add one drop of Locktite to the threads of the lug. Screw the lug with spacer into the stud and snug down the lug.

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 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.

[ILLUSTRATION OMITTED]

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.
