Anybody know where I can get a 20" barrel for my M16 build (it should have a fixed front sight)?

It can also be a complete upper. And no, I don't want to buy the DA556 rifle...

Good luck, for my XM-177 build I bought a Norc 14-5" barrel and got the .625 FSB from Brownells. I then drilled and ream the barrel/FSB for the taper pins. The only option I see is if a site sponsor can import from Brownells. I ordered a barrel from Brownells about 3 years ago. I had to fill out a bunch of paperwork and It only cost me $10 extra on top of the actual price. I think today it cost a couple hundred bucks extra, not to sure.

CGN'er Travis Bickle raves about he good they are. 1-9 or 1-12 twist. I got one, just need the taper pins machined.

The DA556 barrels are excellent.
I will personally attest to that.
I had an SP1 Colt on my M16A1 clone and last year swapped it for a brand new DA556 1:12 after some muddling with the FSB pins lol....
The DA556 barrel shoots the same bulk 5.56 55gr AE ammo better than the Colt barrel ever did by far.

Say what you want about Norinco but their AR barrels are good to go.

OP you would do better to buy the barrel in Machman's link and have it drilled to match whatever FSB you source. It will be cheaper and easier than dealing with the Norc Taper pins if you choose to swap the handguard cap/barrel nut etc in the long run.
Ask me how I know lol :(
 
Pure barrel you can buy a fn chf or a bcm non chromelined. Fsb/gas block you can buy separately. Gas tube is same story. Rainier or colt.

Or you can check armseast and get a stag upper.
