Let’s Talk About Aero Precision .936 Low Profile Gas Block AR15/AR 308 Black Nitride
The Aero Precision .936 Low Profile Gas Block AR15/AR 308 Black Nitride is a key component for building or upgrading an AR platform rifle, whether it’s chambered in AR15 or AR 308. Manufactured by Aero Precision, this gas block is designed for barrels with a .936-inch outer diameter at the gas block journal, offering a low-profile design to fit under most free-float handguards. Its black nitride finish provides enhanced corrosion resistance and durability.
I decided to upgrade my AR-308 build with a heavier profile barrel, but I had trouble finding a gas block that would fit underneath the handguard I wanted to use. The height of other gas blocks was too great, causing interference. I wanted a reliable, low-profile gas block that wouldn’t break the bank and would still deliver top-notch performance.
Upon unboxing, I was immediately impressed by the solid feel and clean finish of the Aero Precision gas block. The black nitride coating looked even and professional, suggesting a high level of attention to detail. The weight, though minimal, felt substantial enough to indicate quality construction.
Compared to other low-profile gas blocks I’ve used from brands like Yankee Hill Machine and Seekins Precision, the Aero Precision model stood out for its competitive price point without sacrificing perceived quality. I chose this one specifically because of Aero Precision’s reputation for reliability and the positive reviews regarding its fitment and finish. Its low profile was also a critical factor in my decision, assuring it would work beneath my chosen handguard.
My first impression was one of cautious optimism, excited about the potential for enhanced reliability and accuracy in my AR-308 build. It seemed like a well-made part, and I was eager to see how it would perform in a live-fire situation.
Real-World Testing: Putting Aero Precision .936 Low Profile Gas Block AR15/AR 308 Black Nitride to the Test
First Use Experience
My initial testing took place at my local outdoor shooting range. I installed the Aero Precision .936 Low Profile Gas Block AR15/AR 308 Black Nitride on my AR-308, pairing it with a new 20-inch heavy barrel and a free-float handguard. The range offered covered lanes, shielding from direct rain but not from humidity.
During the first session, I experienced consistently smooth cycling and reliable gas regulation. The rifle felt well-balanced, and there were no noticeable issues with gas leakage or improper cycling, even after several magazines of rapid fire. The low-profile design proved its worth, fitting perfectly under the slim handguard without any contact or interference.
Installation was easy and uneventful. My first experience was that the included set screws held up tight and showed no signs of loosening, even after several magazines.

After several months of regular use, including approximately 500 rounds fired, the Aero Precision .936 Low Profile Gas Block AR15/AR 308 Black Nitride continues to perform flawlessly. I’ve used it in various weather conditions, from hot, dry days to cooler, slightly damp afternoons, and it has consistently delivered reliable gas regulation. There have been no malfunctions or cycling issues attributed to the gas block.
The nitride finish has proven durable, showing no signs of rust or corrosion, even after being exposed to moisture and cleaning solvents. The set screws remain secure, and I haven’t needed to re-tighten them since the initial installation.
In comparison to other gas blocks I’ve used in the past, the Aero Precision model stands out for its consistent performance and ease of installation. Some cheaper options often require more tweaking to get the gas system dialed in correctly, but this one worked perfectly right out of the box.
