WTS a brand new, straight from the factory 16" RRA A4 upper with mid-length gas system, chrome-lined barrel (1:9 twist), free float quad rail and weaver gas block. Comes complete with CH and BCG - just snap on your complete lower and you are good to go. $Sold FTF preferred in the Orange County area but will ship for an additional $20.


The upper still has factory oil on it which can look like discoloration in the pictures.
