| The
Mossberg 500 shotgun comes with a captive magazine bolt, which
is retained by a star washer attached to the bolt threads. The
purpose of this design is to prevent loss or misplacement of
the bolt. To install the side sling adapter the star washer
retaining the magazine bolt must be removed. This will eliminate
the captive bolt feature, but will not affect safety or reliability
of the weapon at all. |
 |
| Remove
your barrel and locate the star washer inside the barrel ring.
Using a small screwdriver pry back the legs of the star washer
until you can free it from the barrel bolt. |
 |
| Remove
the star washer from the barrel bolt and discard the washer.
You may now continue with your sling installation. |
