Dear Half-Mast,
We are trying to
order a canvas cover
for our M66 ring mount,
but can’t find the NSN
for one. Can you help?
CW2 P.R.
Dear Chief P.R.,
Certainly. Order an M66 cover with NSN 1005-
00-707-0725. It costs around $275. You can also
now order a plastic “shower cap” cover with NSN
1005-01-610-9108 for around $300.
