The Aero Precision complete AR-15 upper (brand part no. APAR502505M3) is built around a 10.5-inch, chrome-lined carbine barrel in .223 Remington/5.56 NATO, finished in matte black and rifled at a 1:7 twist rate. It comes with an A2 front sight post, 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 for a shorter-barrel AR-15 configuration. As with Aero’s other complete uppers, this assembly does not include a bolt carrier group or charging handle, so those need to be added separately.
