I’m noticing that DD rifles from about 2019 don’t have a forging mark on their lower receivers and also their raised fencing around the magazine release is a bit different from mil-spec. I know DD used to use Cerro, Anchor Harvey, etc, but why are there no forging marks on the lower receiver now? Did DD start using some proprietary forging now?

Also, it’s just the lower that doesn’t have the forge mark now. The upper still has it.

Best place to find out for sure.

No forge mark on mine but it’s an old 5.56mm marked lower.

One of the specified locations for the forger's mark is on the web of the grip.  In that location it gets machined off.

Are there DD lowers that do have forge marks?  

I don't think I've ever seen a forge mark on a lower.  Not even on an 80%.

Usually removed while machining.

I've had Colt, Spikes, and Anderson with the Cerro forge marking still intact.

I feel like lowers with forge marks are a rarity. I don't think any of mine have them.

Just bought a MK18 directly from DD a couple weeks ago.  Has Anchor Harvey forge mark.  Both of my Andro’s have Brass Aluminum markings.

Edit.  I missed you were talking about lowers.  I’ve never seen a lower with a forging mark.

The current DD lower's fencing around the mag release is unique and not seen on other ARs. Isn't that fencing directly on the raw forging? What forging would have this style of fencing?

Note that the 6920's fencing rear side is vertical.
