Aero Precision 20″ Complete AR15 A2 Carry Handle Rifle Upper – .223/5.56



Aero Precision 20″ Complete AR15 A2 Carry Handle Rifle Upper – .223/5.56

Perfect for M16 AR15 builds, the Aero Precision Complete Carry Handle 20″ Rifle Upper is one of the smoothest shooting uppers on the market. Simple and robust, this upper uses a pinned front sight post, removable carry handle rear sight, and bayonet mount to get those M16A4 aesthetics and functionality. Aero Precision excels at producing fantastic products at great prices.

Barrel and Gas System

Using a 20-inch barrel, the .223/5.56 round gains nearly maximum velocity, meaning lighter rounds like 55gr projectiles are as practical or more effective as heavier projectiles in shorter barrels. A good comparison is that shooting a 55gr projectile out of an AR15 barrel under 14.5 inches can have problems penetrating car doors, as 55gr out of a 20-inch barrel can penetrate through level 4 armor plates.

The Rifle-length gas system is the longest out of all AR15 gas systems, with many benefits over shorter ones. Firstly, the gas system uses a pinned front sight post as a gas block. This already makes the gas system more durable over non-pinned gas blocks. The Rifle-length gas system is the softest recoiling and smoothest functioning gas system you can ever get.

The barrel is 4150 Chrome Moly Vanadium with a QPQ corrosion-resistant finish. The muzzle device featured on this upper is the tried and true A2 “bird-cage” flash hider. This complete upper does not include a Bolt Carrier Group or Charging Handle.
