U
nits are still trying to make unauthorized modifcations to their M16s and M4s.
That will get you in trouble and could endanger you, your unit and your weapon.
The latest unauthorized modifcation that has reared its ugly head is converting
an M16 to something called a squad designated marksman riFe. This involves a
di±±erent barrel and trigger group. Needless to say, this is NOT authorized.
The only time a weapon can be modifed is i± the Army has approved a modifcation
work order (MWO). This is spelled out in Para 3-1e o± AR 750-10: “Commanders
will not allow their equipment to be modifed unless there is an o±fcial MWO.”
MWO 9-1005-319-30-1 authorized units to convert M16A2s to M16A4s. That
MWO has expired. No more M16A2s can be converted.
What items can you mount on your M16/M4? Only those listed in TM 9-1005-
319-10 and -23&P. The
Small Arms Integration Book
also lists authorized equipment.

I± your M16A2 uses the M5 adapter rail system ±or mounting, remember that the
rail system is considered AAL. I± the M16A2 is turned in, you need to keep the rail
system and reinstall the original handguards.
Do what the M16/M4’s TM tells you to and you and your weapon will do fne. Go
beyond that and trouble is near.
Dear Half-Mast,
Can you store M16 rifles and M4/M4A1 carbines in the M12 rack with
sights like the CCO and ACOG attached?
SSG E.M.
Dear SSG E.M.,
Yes and no. If a locking bar is added to the M12 rack, it is possible to store M16s
and M4s in the rack with the sights installed. (The instructions for your support to
make the locking bar are in TM 9-1005-319-23&P (Nov 08). After the bar is added,
the rack must be certiFed by your local TACOM logistics assistance representative.)
But it is also possible to remove the sights from the weapons stored in the rack,
which leaves them vulnerable to theft. So your best option is to remove the sights
and store them in a locked cabinet or locker inside the arms room. That way they’re
under double lock and key.
