    Uncompromising quality meets unbeatable value. The AT3 Tactical FFQR Complete Carbine Upper.

    Our 5.56 Upper featuring a 16" Carbine Barrel and AT3 Pro Series Free Float Quad Rail.

    About Our Uppers

    The two most critical parts of a reliable, accurate AR15 are the bolt carrier group (BCG), and the barrel.

    That's why the FFQR Series feature a Spike's Tactical BCG and VooDoo Innovations Barrel - two of the most respected names in the industry. The flat-top upper receiver is a Mil-Spec Forged Upper made by BCM.

    The free float quad rail, muzzle device, and charging handle are configurable to suit your needs. 

    All of our uppers include:
