Fair price for used AR upper?

[rgillis]

Can anyone give me an idea of what would be a fair price for a used Bushmaster M4A3 upper?

If it's in nice condition complete with bolt carrier group, I'd say $400 absolute tops. You can buy new uppers for less than that amount from a couple of places.

I appreciate the info, that's just about what I thought.

thanks

One of my favorite vendors (PK Firearms) has a Bushmaster complete flat top 16" upper, less carry handle/rear sight, for $515.

So yeah, assuming great condition and low round count, $400 (and I'd prefer it come with the carry handle or rear sight for that). Higher round count, no rear sight, lots of wear, that price goes down accordingly.
