I'm kind of new to the AR scene so I'm not really sure what if any difference there is to the different manufactures of A3 uppers. I currently have a Bushmaster XM15-E2S that has the A2 upper. I want to change it to the A3 upper so that I can use modular rail accessories. Checking Bushmaster's pricing sayagainst CMMG is roughly $70 dollars more.
Is there really that much difference to warrant the price?

M4 feed ramps or not.
Check your current upper. If the feed ramps are cut into the barrel extention only, then you need one without M4 ramps. If they are cut into the barrel extention and the upper itself then either will work. But I do recomend getting an upper with em, to take full advantage of the reliability bonus.
Im thinking if you have an A2 upper, you prolly don't have M4 feed ramps.

Hunting on the internet I came across a link that pretty much answer my question. Thank you to those who responded to my inquiry and here is the link(s)
Amazing the price difference just because of what name is stamp in the side of a piece of metal.
