I have an A2 front sight block but no front sight post, detent, spring, etc.
What exactly do I need to complete this A2 FSB and would brownells be the cheapest source?

You answered your own question. Sight post, spring and detent are needed. Order from who has the cheapest shipping.

You'll likely get a better deal if you order as a kit.

RRA A2 front sight parts kit:

That's the easy part.... the tough (and expensive) part is pinning it ($80-$110 job).
