I thought so at first too but the stabilizer is shorter than that of the M22 and is missing additional fuse assembly that the M22 has. In fact it measures at 9 7/8 inch which is the same length for the M23 in this link: TM
GRENADES, RIFLE: SMOKE, GREEN, RED, VIOLET OR YELLOW, M22 AND M22A2
Type Classification:
Obs. MSR 11756003
Use:
For signaling and for laying smoke screens.
Produces green, red, violet or yellow smoke.
Description:
The M22 and M22A2 consist of three basic parts: a
steel stabilizer assembly, an integral fuze and a body.
The fuze is a mechanical impact-igniting type. The
body is filled with a burning-type smoke charge which
contains a dye to color the smoke. The surfaces of the
smoke charge within the body are coated with a starter
mixture charge to facilitate ignition. A small opening or
air hole in the nose of the ogive is covered by a nose
closing plug.
Difference Between Models:
The M22 and M22A2 grenades differ only in minor
features.
I'd say it's an M22 as it's the only one of it's type to note a "nose closing plug" vs tape.
I replied once but for some reason when I edited something, it became dark and almost unreadable. So I'll try again.From TM-43-0001-29

Can't move it. It is solidly in place. It also looks like it been machined, not just something stuck it to fill a hole. It's been inserted from the inside too and there is no evidence of tampering on the bottom. It would not have fit through on of the smoke release holes.I think it is an M23A1, but someone has put something in there for whatever reason, does it move around? Can you remove it??
