16 Inch Lightweight AT3 Upper with 15 Inch Handguard – Gray Cerakote

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

  • Quality Where it Counts – premium components like Faxon Firearms 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 money by bundling, and save time by letting us do the assembly!

This fully assembled AR-15 complete upper includes:

16″ Ballistic Advantage Pencil Profile 5.56 NATO Barrel (with AT3 low profile gas block & midlength gas tube)

Ballistic Advantage Middle Pencil Barrel

 

The Ballistic Advantage barrel we use for this assembly has a 1 in 7 twist rate, perfect for stabilizing just about any 5.56 load you can feed it. The lightweight Pencil profile offers far better handling than front-heavy “Government” profile barrels, and the Midlength gas system produces less felt recoil.

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. This upper is assembled with a lightweight Ballistic Advantage barrel for excellent performance and handling.

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.
