Post ban upper 20"

Garanteed BP just had this inserted in to his dream, probably saying right now "Doc" Check your PM...

Yep, BP Tactical is your man give him a call, quality, fast and affordable.
If you call him this morning, he may even have it done for you yesterday.

Front sight bases are not all the same. It's sometimes a PITA to find one that will fit because the pins/pin holes are not the same from gun to gun. Threading the barrel isn't a problem.

+1 on having BPTactical thread the barrel. I personally could care less about a bayonet lug myself. I think bayonet tactics are a thing of the past. Others may disagree with me. If I was running around with a rifle with a knife hanging off the front I would probably just hurt myself.

while not functional for my needs. if you want to keep "that look" then you will need to change out the front sight assembly.

Ban era barrels are easily threaded to their pre ban glory. By the time you find a TAT and spend the money trying to find a die I will have it done for you.
A couple of different ways to deal with replacing the FSB- I can either use oversized pins or do the "National Match" mod.
Check your PM's DOC.
