Seems like everyone does m4 extensions on everything.

A massive shame windham is gone, the a2 barrels they made were superb

I have one of those on an A2 I put together this summer. Haven't shot it yet.  But, I now understand they have unmarked "F"-height front sight bases.  So, it's actually more an A4 barrel than an A2.

Quoted by them as 550$ for a complete barrel. Kinda pricey

Yeah that's quite a bit. Even supplying your own parts and sending it to John Thomas probably wouldn't be much cheaper. Also, other than retrorifles.com, JSE Surplus is the only place I've found that sells non-F-marked FSBs.

Apparently Windham is coming back but who knows what they'll sell post bankruptcy.

Windham coming back? I hope.

I have one of their barrels on my spare parts a2 build. It's a nice shooter

I emailed Green mountain (who WW got their barrels from) about getting a 20" barrel with an m16 extension, but no response yet. I don't see why not. They make 12" barrels with m16 extensions, I don't see why a 20" with one is too hard.

Signed up for the notification when they are back in stock.

Side note: Is it possible to swap out the front FSB for an F marked without any problems?

Not always - depends on how the maker drilled the pin holes on the FSB and if (big IF) they align with the similar relief cuts for those pins in the barrel.  

As a general rule of swapping FSBs between different barrels is typically that is a "Sorry - close but both pins doesn't align"

In the Q&A down at the bottom of the page, Brownells says that even the 20" version has M4 feed ramps.

May I suggest the EE here? Rifle barrels pop up often, a lot of times NOS.

Fulton has a minor sale on A2 barrels. Still pretty expensive but the complete barrel is decently cheaper than what fadedsun was quoted a few months ago.
$436 for complete
$297 for stripped

Not sure if it has a rifle extension but Windham is manufacturing A2 barrels again.  Not in stock though.

Virtually everyone is using F height sights, whether they are marked or not.
