Aero Precision Complete Upper 5.56 NATO 20" A2 Profile – AR-15 Platform

This Aero Precision complete upper assembly delivers classic A2 configuration in 5.56 NATO, built around a 20-inch government profile barrel. Chambered for 5.56 NATO (accepts .223 Remington), this upper fits standard mil-spec AR-15 lower receivers and ships ready to install. The longer barrel length maximizes velocity and effective range for precision shooting and longer-distance applications.

Constructed from 7075-T6 aluminum with a black anodized finish, this upper includes a complete bolt carrier group and charging handle. The A2 profile barrel features a 1:7 twist rate for stabilizing heavier projectiles. Installation requires basic familiarity with AR-15 platform assembly—torque specs and proper headspacing verification recommended.
