Not really any differance. The M1Cs the DCM come with the sight base but no mount or scope.

Neither the MIC or D are match grade, (not like the M21 or M14 version).

If you are looking for a collector and you need the M1C, then thats a good price. If you are looking for a shooter, and just want an M1, you'd be better to go the Service Grade M1.

If you are wanted to put together a M1 for the CMP GSM Vintage Sniper Rifle Matches, CMP sells the "D" model for $1500. Still you have to find the Mount, Cheek Pad, M-84 scope, and Flash Hider which you also have to do for the M1C.

As for which is better, the M1C or M1D, it depends on what you want. Both are good rifles.

I ran sniper schools for the National Guard when we still used M1C & Ds, we had both. There was no advantage of one over the other, both were good rifles and capable of engaging man size targets up to 900 yards after the rifle is sighted in.

Some complain that the scope slips in the D scope rings. That was a simple fix. Put a dab of rosin powder on the scope before you tighten it down.

Like I said, if you are collecting, the $3000 for the C is a fair price. If you want a shooter to put together a M1 Sniper Rifle, the cheaper $1500 "D" model is the way to go.

The best of all worlds would to have one of each.
