The upper you are looking at has a free floating handguard and appears to have a quad rail on it already.

 

Edit: The picture shows a quad rail but it says knurled tube. Be careful!

I'm sure the quad rail is an extra and they should install it if it's a free floating quad rail.

They appear to be the same upper. The cheaper one is without a BCG and charging handle which accounts for the price difference. I'd call and clarify.

yes i went back and read some more . what should i be conserned with on theese uppers? or what dont seem ok?

Do yourself a favor and don't buy a non-name upper. If you can't tell what they are even selling (and I can't because the pictures and text don't match) then I sure as heck can't tell what quality parts they put in. For the same money you can buy a Spikes upper which may not be the best stuff but it is decent stuff:

Reed- Do what Vlad said or go where I told you and atleast you know what you're getting. At JSE you can build your own and see what the price is for what you are getting.
