7.62 upper on Daniel Defense DD5 V5 6.5 CM

[MerlinMc]

I have a Daniel Defense (DD) DD5 V5 6.5 CM which has been a great rifle.

Can a 7.62 Daniel Defense DD5 V4 7.62x51 upper be swapped directly onto the lower of the above rifle?

Thanks!

Yes, DD advertises their DD5 complete uppers as replacements to drop-on to their lowers for the large frames.


I like what they did with the cam helix on their BCGs, by extending its in-line travel before camming over, and thereby keeping the bolt locked longer.

I think I remember that they were selling complete uppers for this purpose. The Daniel Defense site doesn’t have them listed (or I couldn’t find them), but EuroOptic does.

@bigjake83 was playing around with the DD5 system as an alternative to the LMT MWS. He would probably be a good source of information if you wanted anything more than plug-and-play complete uppers.
