tually, but until then
use this procedure to
immediately
inspect
all your unit's M2
buffer bodies…
1.
Check that the lock depressors are
securely attached to the buffer body.
It's OK for the depressors to move as
long as they don't move so much they
interfere with the M2's functioning.
If the lock depressors need to be
retightened, use a center punch on the
center of the depressor's rivets.
2.
Never stake or swage the buffer
body to prevent movement of the
lock depressors. If the buffer body
has been mistakenly staked or
swaged already, it's OK to keep using
the buffer as long as the staking or
swaging doesn't interfere with the
M2's functioning.
3.
Make sure the buffer body lock
can't be removed. If necessary, direct
support can swage the lock with the
directions in the next column.
5.
Check for any missing, damaged,
or worn parts.
Any needed repairs to the barrel
buffer assembly should be done by
direct support with authorized parts.
