AERO PRECISION - AR-15 ASSEMBLED UPPER RECEIVER 16" 5.56MM MID-LENGTH

The AR-15 5.56mm 16" Mid-Length Upper Receiver comes fully assembled, lacking only a charging handle and bolt/carrier group, for shooters who prefer to choose those components to suit your specific needs. The 16" barrel of high-grade chrome-moly-vanadium carbon steel has a tough, corrosion- and scratch-resistant black QPQ finish (all other steel parts are Parkerized). It’s chambered for 5.56mm NATO military ammunition, so it will safely handle civilian .223 Remington ammo too.
