First Impressions of Dark Storm Industries Pinned .750 diameter Micro Gas Block
The Dark Storm Industries Pinned .750 diameter Micro Gas Block promises to be a compact and reliable solution for AR-15 builds requiring a low-profile gas block. Dark Storm Industries aims to provide a complete kit, simplifying the installation process. It includes not only the gas block but also essential components like the taper pin, drill bit, and reamer.
I’ve been customizing AR platforms for over a decade, often struggling with finding gas blocks that truly fit under slim, free-floating handguards. Many “low profile” options still protrude, limiting handguard choices. The promise of a micro-sized, pinned gas block immediately caught my attention, as I’m seeking to build an incredibly streamlined AR pistol.
Upon unboxing, the Dark Storm Industries Pinned .750 diameter Micro Gas Block presents itself as a solid, matte black piece of steel. The machining appears clean, and the included hardware seems appropriately sized. The overall weight feels substantial, hinting at durable construction.
Compared to other low-profile gas blocks I’ve used, such as those from Aero Precision and Seekins Precision, the Dark Storm Industries option visibly stands out due to its significantly smaller footprint. This reduced size is precisely what I was after for my compact build. The pinned installation also feels more secure than relying solely on set screws, addressing a recurring concern I’ve had with gas block slippage under heavy use.
My initial impression is one of cautious optimism. The small size and comprehensive kit are promising, but the real test will be the installation and subsequent performance at the range. If it performs as expected, this could be a game-changer for my future builds.
Real-World Testing: Putting Dark Storm Industries Pinned .750 diameter Micro Gas Block to the Test
First Use Experience
I tested the Dark Storm Industries Pinned .750 diameter Micro Gas Block on a newly assembled 10.5″ AR-15 pistol chambered in 5.56 NATO. The installation took place in my workshop, followed by an initial range session at an outdoor shooting range. Weather conditions were dry, with temperatures hovering around 75 degrees Fahrenheit.
Installation required careful drilling and reaming to properly seat the included taper pin. The provided drill bit and reamer worked adequately, but required patience and a steady hand to avoid damaging the barrel. After installation, the gas block sat securely against the barrel shoulder, well concealed under a slim M-LOK handguard. The rifle cycled smoothly with both .223 and 5.56 ammunition.
After the first 100 rounds, I did not experience any noticeable issues with gas leakage or cycling malfunctions. The micro profile allowed the handguard to sit flush against the upper receiver. It provided a clean and unobstructed appearance.
Extended Use & Reliability
After several months of regular use, including multiple range trips and a weekend carbine course, the Dark Storm Industries Pinned .750 diameter Micro Gas Block continues to perform reliably. I have fired approximately 1,000 rounds through the rifle since installing the gas block.
There are no signs of wear and tear on the gas block itself. Furthermore, the taper pin remains securely in place. Regular cleaning involves a quick wipe-down with a CLP-soaked rag after each range session. The bore of the gas block is easily accessible with standard cleaning tools.
Compared to my previous experiences with set-screw-only gas blocks, the pinned installation of the Dark Storm Industries gas block provides a significantly greater peace of mind. It eliminates the risk of the gas block shifting or loosening under prolonged use and high heat. I consider it a solid and dependable upgrade over standard options.
