Dear Half-Mast,
I recently replaced a broken
standard M4 buttstock, NSN
the new enhanced buttstock,
I was told later I shouldn’t
have done that because the
enhanced buttstock is AAL.
Because of that, if the M4
is turned in or transferred
it must have the standard
buttstock. Is that true?
SGM T.F.
Dear Sergeant Major T.F.,
Sure is. If you use the
enhanced buttstock, you need
to keep the standard one for
turn-in or transfer of the M4.
The enhanced buttstock has
a rubber recoil pad, holds
a battery, and has a sloping
cheek weld that gives a
better sight picture. But it
is AAL.
Rack slots need to be cut like this

1.±
Remove all weapons from the rack and move it to a well-
ventilated area where you can get at all sides of the rack. Be
sure to wear goggles and a mask while cutting and painting.
2.±
Measure and mark each section to be cut: 2 inches from the
top down and 1½ inches from the front to the back.
3.±
Use a 5-in angle grinder with a 5-in cutoff wheel attached to
cut and remove each marked area.
4.±
Use a reciprocal saw to cut any section not accessible with
the angle grinder. File off any rough edges.
5.±
Paint exposed metal areas with a paint that matches what’s
already on the rack. Let the paint thoroughly dry.
6.±
Put the M12 back in place. Make sure the M12
securely locks the weapons in place.
