It doesn't need to be amazingly top-of-the-line. I'm satisfied with the BCA uppers that work for me, that lots of AR purists and snobs shite on.

I simply want a plinker that "looks" like a traditional Vietnam era M16, with the fixed stock, triangular foregrip, and the integral carry handle.

What's the cheapest I can put one together? Do I need a 20" barrel, or was it 18"? And is that the 3 prong flash hider, or a birdcage?

I'm not going to buy a Brownell's version for over a grand, I want to keep this around $500 or under.

Not sure about sources, but you want a 20" barrel with the birdcage. If you want to be really historically accurate, try to find a birdcage that has the slots all the way around. At some point they started making them with the bottom solid so it wouldn't puff up dirt/dust if you were in the prone. You have to index them with crush washers so the solid part is aligned correctly; I don't think the old ones were indexed.


ETA I'm a dummy, the birdcage wasn't adopted until the A2. I thought they were using it during the latter part of the war.

Check out Palmetto State Armory. They have some good budget build kits.

JSE Surplus carries the complete uppers, but looks like they are sold out right now.

You need a pencil barrel. that will probably be the part that is OOO, the rest should be readily available.

Bump...

I've lined up a fairly decent budget project. Not truly retro, but decently close, at least for appearance's sake\
