Few quick questions on a topic that's probably been beaten to death:

I recently sold my LE6920.  Before selling it I noted that it had a Diemaco upper (that was purple) and had the "M4" marking on the front of the receiver below the carry handle.

Another officer recently obtained his 6920 with a Continental (correct? C with Keyhole) upper and his does not have the "M4" stamp.

Can anyone out there who's recently received their rifle tell me if this coincides with how their rifles are marked?

Also, since the surge in demand, does anyone know if Colt is using one upper manufacturer (possibly incorrect terminology) more than another?  For example, are all the recently produced uppers from Continental or is it still whichever upper they happen to have on hand?

One last question.  I did not have to move my rear sight from center at all for my rifle to be zeroed.  Has this been common for those with rifles?

Thank you for any responses.

Most rifles are set to mechanical zero at the factory, which is usually close enough to get you on paper.  Often folks have to bump it over a few clicks one way or another.

Diemaco uses a stlized (angular) "D" as their maker's mark. As Diemaco is a licensed producer of Colt parts Colt uses their parts freely in their assemblies.

The keyhole mark belongs to Cerro Forge and designates who made the raw forging. The "C" on the upper is from Colt, who did the machine work.

Does the other officer's 6920 have M4 ramps? Are they anodized or in the white?

Minimal movement from mechanical zero is common on Colt rifles.

Thanks for the replies.

The officer should be down tonight so I'll check on the ramps and their condition.

My LE6920 have the M4 feed ramps.  Can't remember any markings, will check later tonight.

I've owned both and my vote goes with Diemaco -- the always mark their rails and forging seems to be more consistent.  They have a great website too....

I just checked the other officer's rifle and it has the ramps and they are anodized or black for what it's worth.
