The Aero Precision AR15 Complete Upper 223 Remington/5.56 NATO Made a Bold First Impression
The Aero Precision AR15 Complete Upper 223 Remington/5.56 NATO isn’t just another AR upper; it’s a nod to the classic M16A4, modernized with Aero Precision‘s renowned manufacturing precision. Featuring a 20″ barrel, pinned FSB, A2 handguard, and detachable carry handle, it promises a blend of nostalgia and modern performance. This upper is specifically designed for those looking to build a reliable and accurate rifle with the classic aesthetics of the M16A4.
My quest for this particular upper stemmed from a desire to build a dedicated long-range AR-15. I wanted something more precise than my 16″ carbine and appreciate the timeless appeal of the A2-style rifle.
Unboxing the Aero Precision AR15 Complete Upper 223 Remington/5.56 NATO felt like stepping back in time. The fit and finish were immediately impressive, showcasing Aero Precision‘s commitment to quality. The weight felt substantial, suggesting durability.
Compared to a modern free-float upper from Bravo Company Manufacturing (BCM) and a lightweight upper from Palmetto State Armory (PSA), the Aero Precision stood out with its classic configuration and robust construction. While the BCM offered enhanced modularity and the PSA was budget-friendly, I chose the Aero Precision for its specific purpose – a long-range, classic-style AR. The retro look combined with modern manufacturing won me over.
My initial reaction was excitement mixed with a touch of anticipation. I was eager to mount it on a lower and see how it performed. This upper isn’t just a collection of parts; it’s a well-executed homage to a classic rifle.
Real-World Testing: Putting Aero Precision AR15 Complete Upper 223 Remington/5.56 NATO to the Test
First Use Experience
My first range session with the Aero Precision AR15 Complete Upper 223 Remington/5.56 NATO was at a local outdoor range on a relatively mild, sunny day. The rifle was paired with an Aero Precision M4E1 lower receiver and a CMC Triggers single-stage trigger. The target distance was set at 100 yards.
The upper performed flawlessly right out of the gate. Using both .223 Remington and 5.56 NATO ammunition, the rifle cycled reliably. The A2 sights were easy to adjust and provided a clear sight picture.
No issues were immediately apparent, although the A2 handguard did get a little warm after several rapid strings of fire. This is typical of the design.
Extended Use & Reliability
After several months of regular use, the Aero Precision AR15 Complete Upper 223 Remington/5.56 NATO continues to impress with its reliability. The finish shows minimal signs of wear, even after being exposed to varying weather conditions. Cleaning is relatively straightforward.
The A2 handguard, while durable, can be difficult to thoroughly clean inside without removing it. This is a minor inconvenience compared to the overall performance.
Compared to my previous experiences with other AR uppers, the Aero Precision stands out for its consistent accuracy and reliability. It consistently delivers tight groupings at 100 yards, and I’ve experienced no malfunctions to date.
Breaking Down the Features of Aero Precision AR15 Complete Upper 223 Remington/5.56 NATO
Specifications
- Caliber: .223 Remington/5.56 NATO. This allows for the use of both common AR-15 ammunition types.
- Barrel Length: 20 inches. This provides increased velocity and improved long-range accuracy compared to shorter barrels.
- Twist Rate: 1:7. The 1:7 twist rate stabilizes heavier bullets, making it ideal for a wide range of ammunition, including 77-grain match rounds.
- Material: 4150 Chrome Moly Vanadium steel barrel with QPQ corrosion-resistant finish. This ensures durability and resistance to the elements.
- Sights: A2 Detachable Carry Handle and A2 Front Sight Block w/ Bayonet Lug. This provides a classic sight picture and the ability to attach accessories to the front sight block.
- Gas System: Rifle Length. The rifle-length gas system offers smoother recoil and reduced wear and tear on the internal components compared to shorter gas systems.
- Handguard: A2 Style Handguard, Rifle Length. This provides a traditional look and feel while protecting the barrel.
- Muzzle Device: Standard A2 Flash Hider. This reduces muzzle flash and helps conceal the shooter’s position.
These specifications are significant because they contribute to the overall reliability, accuracy, and handling characteristics of the upper receiver. The 20″ barrel and rifle-length gas system, in particular, offer a smoother shooting experience and improved ballistic performance compared to carbine-length AR-15s.
