Nothing against Denny, but he is having barrels produced and then ASSEMBLING custom uppers.
The barrels are not necesarily custom when you have them made 50 pieces at a time.
They might be non-standard and they are likely very good barrels, but a true "custom" barrel is a 1-of-a-kind until someone else decides they want something just like it and copy it.
A custom barrel can be ANYTHING you want, with no limits as to what the market has to offer.

Define affordable.

Take Denny's $295 stainless recon barrel since that's the first one you linked.

My stainless steel match grade barrels run $375.
Yes, that's certainly $80 more, BUT you can get ANY twist, ANY length, ANY profile, ANY special configuration like dual gas block seats for building an SPR type setup with a hidden gas block and a flip-up front sight out in front of a rifle length handguard.
Did I mention ANY muzzle thread spec so you can put a suppressor on it that you happen to own for your other gun?
Did I mention that YOU can specify the headspace you want?
Precision reloaders might want a chamber that does not beat up brass while most guys want a chamber on the long end of specs like a 5.56 chamber for the added reliability.

That $80 is not so bad when you think about it that way now is it?

Denny-

I was not aware that you offered completely custom barrels as well.
I stand corrected.
