AT3 Complete Upper assemblies are Built for Accuracy and Reliability – Guaranteed.

  • Quality Where it Counts – premium components like Ballistic Advantage barrels, and AT3 Tactical’s handguards and uppers. Don’t settle for “bargain uppers” with unknown components.
  • Guaranteed Reliability– Carefully assembled before shipment, and backed by the AT3 Lifetime Warranty
  • Unbeatable Value – Unbeatable quality in the price range. Save by bundling quality parts – already assembled vs. purchasing the components separately.

This fully assembled AR-15 complete upper includes:

Faxon Firearms 16″ Light Tapered 9mm Barrel

Faxon Firearms 16 Inch 9mm Light Taper Barrel

With no need for the traditional AR15 gas system, and far less heat and stress, 9mm blowback uppers like these don’t need a heavy barrel to perform great.  Faxon’s 10.5″ Light Tapered Barrel  ensures that your pistol caliber AR is easy to manipulate, and will hold up under heavy use.

 

AT3 SPEAR 15″ Free Float M-LOK handguard

Unique slim and lightweight design with M-LOK attachment points. Rock-solid 6061 aircraft aluminum handguard that withstands the harshest treatment. 5-slot M-LOK-to-Picatinny rail section included

3 reasons why AT3 Complete Uppers are better than the rest.

1 – Quality Where it Counts

The single most important component of an accurate AR-15 is the barrel. AT3 uppers are built using barrels from top brands like Ballistic Advantage and Faxon Firearms, for excellent performance and accuracy.

But the quality doesn’t stop at the barrel. Our AT3 handguard and upper work together to provide superior accuracy, meaning this upper assembly offers quality without compromises.

Many of the “bargain” complete uppers on the market source their parts from the lowest bidder – at the expense of accuracy and reliable function. AT3 is committed to using only top-quality components in our upper assemblies.

2 – Guaranteed Reliability

AT3 complete uppers are assembled with strict quality controls and carefully packaged for delivery to the customer. All AT3 complete uppers offer a Lifetime Warranty – if you ever have an issue, let us know, and we’ll make it right. It’s that simple.

3 – Unbeatable Value

When you buy a complete upper, you’ll save money and parts and assembly vs purchasing the components separately. Our complete uppers are not the cheapest on the market, but they deliver unbeatable quality in the price range. We sell direct to the customer, and cut out the middle-men, to deliver the best value in AR-15 upper assemblies.
