5.56x45 Nato Assembled Upper Receiver For Ar-15 - 5.56mm 16'''' Bbl M4 Comp Uppr Rcvr W/Brn Bcg & Charge Handle

Aero Precision's AR-15 5.56mm 16" Carbine Upper Receiver closely resembles the military's M4 flattop upper and comes fully assembled. The charging handle and bolt/carrier group are omitted, since AR-15 fans who assemble their own rifles usually prefer to select aftermarket components that suit their specific needs. Why pay for parts you're going to replace? The AR-15 5.56mm 16" Carbine Upper Receiver features a 16" barrel of high-grade chrome-moly-vanadium carbon steel with a tough, corrosion- and scratch-resistant black QPQ finish (all other steel parts are Parkerized). It's chambered for 5.56mm NATO ammunition, so it will safely handle civilia Mfg: Aero Precision
