One their website, you have the option of upgrading the "Current smooth side upper receiver to the A3 style upper receiver". Im trying to determine what exactly the difference is between the two. It looks like the picatinny rail on the A3 just has a lower profile. Why would someone want that? Doesnt that require you to get raised rings if youre going to mount a scope?

It includes the dust cover and forward assist. The FA is not a big deal, but you want the dust cover.

Get the A3.


ETA: I get DPMS "Dealer" pricing but I ordered min fro rguns.net because it was only a few bucks more and in stock.
