Thinking of doing 7.62x39. Is it really finicky? I need to pay for assembly. And I’m not that patient. Anything I should do to avoid having to debug and raise the probability of working first try? TNA or MRA bolt/barrel combo most likely since price is nice there and I can splurge on a trigger then.

"Arguing with idiots is like playing chess with a pigeon..... No matter how good you are, the bird is going to s#!t on the board and strut around like it won anyway."
there's lots of info about the 7.62x39 not being a very reliable cartage for the AR pattern design.
If you wanted something similar (arguably) I'd look into 300BLK. MRA has barrels on sale, and it uses the same bolt as .223
Its impossible to use a standard ar15 barrel extension and bolt for the 223 wssm. The bolt would have no material between the bolt face and lug. Dtech is using what seems to be a modified ar10 bolt which requires a custom barrel extension and a proprietary upper receiver. There would be next to nothing for material in the barrel extension if you made it fit a standard ar15 and with the pressures the wssm cases run you would be shearing lugs off left right and center.
Is there an upper out there in 223 wssm that fits a standard ar15 lower? Yes there is. Can the parts be swapped to the modern sporter? No they cant. The fastest 22 caliber cartridge that will fit in the modern sporter is the 22 grendel. Which gives up very little to a 22-250 as is and it burns less powder. The 223 wssm is also a lot longer than the 22 grendel.
From what I've read is that they use an ar10 sized barrel extension and an ar15 upper that is the same size as the ar10 where the barrel goes. So in conclusion no you can not shoot 223 wssm out of a modern sporter. Well you could but just once
Bummer but thanks for the good explanation of what they do to make it work.
I want to do something different with my second upper... 30 ar is impossible to get a barrel and bolt for any more. I don’t really want to make brass.
Maybe 7mm Valkyrie if they get the Starline brass going.
