The Aero Precision complete AR-15 upper (brand part no. APAR502505M65) is a standard upper receiver built around a 16-inch, chrome-lined 5.56 carbine barrel in .223 Remington/5.56 NATO, finished in matte black. Rifled at a 1:7 twist rate for compatibility with heavier bullet weights, it comes with a pinned front sight base, an A2 flash hider, a Magpul MOE SL handguard, and a carbine-length gas system, giving builders a complete, ready-to-mount upper assembly. The complete upper does not include a bolt carrier group or charging handle, so builders will need to add those separately to finish the rifle.
