First Impressions of Caracal CAR816 A2 Patrol 5.56x45mm NATO Complete Upper
The Caracal CAR816 A2 Patrol 5.56x45mm NATO Complete Upper is an intriguing offering in the crowded AR-15 upper receiver market, promising a reliable short-stroke gas piston system and impressive accuracy. Manufactured by Caracal, this complete upper aims to deliver exceptional performance and durability, built with high-quality materials like Carpenter 158 bolt and 4150 CMV barrel. I was drawn to this upper because of its gas piston system, which I wanted to test against my direct impingement rifles for cleanliness and reliability in adverse conditions.
For years, I’ve been a staunch supporter of DI AR-15s, but recent deployments to dusty environments made me question the long-term reliability of the system. I needed an upper receiver that could withstand harsh conditions and maintain consistent performance without constant cleaning. The Caracal CAR816 A2 Patrol Complete Upper appeared to be a potential solution.
Upon unboxing the Caracal CAR816 A2 Patrol Complete Upper, I was immediately struck by the solid feel and clean lines of the design. The weight felt appropriate for a piston-driven system, not overly heavy but substantial enough to inspire confidence. The nitride finish appeared even and durable, suggesting good corrosion resistance.
Compared to my existing Daniel Defense and Bravo Company Manufacturing (BCM) uppers, the Caracal CAR816 A2 offered a noticeably different aesthetic, particularly around the gas block and handguard. I was initially skeptical of deviating from my trusted brands, but the promise of enhanced reliability and the positive reviews I had seen convinced me to give Caracal a try. My first impression was one of cautious optimism – I was excited to put this upper through its paces and see if it could live up to the hype.
Real-World Testing: Putting Caracal CAR816 A2 Patrol 5.56x45mm NATO Complete Upper to the Test
First Use Experience
My initial testing of the Caracal CAR816 A2 Patrol Complete Upper took place at my local shooting range, which offers both indoor and outdoor lanes. I mounted the upper on a proven lower receiver with a quality trigger and buffer system. The weather was mild and sunny, perfect for an initial sighting-in and familiarization session.
I ran several hundred rounds of various 5.56x45mm NATO ammunition through the Caracal CAR816 A2, including M193, M855, and some heavier 77-grain match ammo. The upper cycled flawlessly with all types of ammunition, exhibiting smooth and consistent operation. The recoil impulse felt slightly different compared to my DI rifles, a bit softer and more linear.
Getting used to the gas piston system took minimal time; the controls were intuitive, and the upper felt well-balanced. I was pleasantly surprised by the accuracy; even with a basic red dot sight, I was able to consistently achieve sub-2 MOA groups at 100 yards. No immediate issues arose during the first range session, leaving me eager to conduct more rigorous testing.
Extended Use & Reliability
After several months of regular use, the Caracal CAR816 A2 Patrol Complete Upper has proven to be a reliable and robust performer. I’ve subjected it to a variety of conditions, including a multi-day training course in a dusty, arid environment and a rainy field exercise. The gas piston system has excelled in these challenging conditions, requiring significantly less cleaning than my DI rifles.
The nitride finish has held up remarkably well, showing minimal signs of wear despite frequent handling and exposure to the elements. Cleaning the Caracal CAR816 A2 is straightforward. The piston system disassembles easily, allowing for quick removal of carbon buildup. Compared to my experience with direct impingement systems, maintaining the Caracal upper is noticeably less time-consuming.
In comparison to my previous experiences with other piston-driven AR-15 uppers, the Caracal CAR816 A2 Patrol has consistently outperformed them in terms of reliability and accuracy. The only point of note is that during the rainy field exercise, I noticed slightly more fouling around the ejection port, but this did not affect the function of the rifle. This upper has exceeded my expectations.
