AT3 SPEAR 12″ 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

AT3 Tactical Billet Upper Receiver

Precision machined from 6061-T6 aluminum, this assembled upper is sleek, with extra material around the barrel extension for superior accuracy. It mates perfectly with our SPEAR handguard and features M4 feed ramps for reliable feeding of ammunition.

KAK Industry Flash Can

One of the most popular muzzle devices for AR15 pistols. The conical shape directs muzzle blast and noise directly in front of the shooter, reducing concussion for the shooter. The standard flash can is only 3.5 inches in length and fits perfectly under the SPEAR handguard.

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

1 – Quality Where it Counts

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.
