Accessories WTB: 20" AR barrel 5.56 with A2 front sight

[8up]

All:

If anyone has a 20" AR barrel that is 5.56, treaded, with a non "F" marked front sight base that is pinned, let me know. Doing a A2 build, and is the last major component I need. If it has the barrel nut, slip ring, and retainer assembly, all the better. Twist is not a issue either. Let me know what you got.

I have a 20" with parts you mentioned. Not sure of the "F" marking. Where do I find that?
