Let’s Talk About Strike Industries Collar Adjustable Gas Block
Adjustable gas blocks are a must-have for any serious AR enthusiast, allowing for fine-tuning of the rifle’s gas system for optimal performance with different ammunition, suppressors, or even to compensate for wear and tear. The Strike Industries Collar Adjustable Gas Block aims to deliver this adjustability with a unique, tool-less collar design that sets it apart from the competition. Strike Industries is known for innovative and aggressively styled AR parts, and I was eager to see how their design philosophy translated to this crucial component.
My interest in the Strike Industries Collar Adjustable Gas Block stemmed from my need for a reliable and easily adjustable gas block for my 300 Blackout build. I wanted to be able to switch between subsonic and supersonic ammo without having to completely disassemble the rifle to adjust a traditional set-screw style gas block. The promise of tool-less adjustment and predefined settings drew me in.
Upon opening the package, I was immediately impressed by the Strike Industries Collar Adjustable Gas Block’s solid, well-machined construction. The black finish was clean and even, and the clamp-on design looked robust. Compared to traditional set screw gas blocks, the collar adjustment system seemed like a significant upgrade in terms of ease of use. My initial impression was excitement mixed with a slight apprehension about the clamp-on design and how well it would hold up under heavy use.
Real-World Testing: Putting Strike Industries Collar Adjustable Gas Block to the Test
First Use Experience
I first tested the Strike Industries Collar Adjustable Gas Block at my local outdoor shooting range, specifically focusing on transitioning between supersonic and subsonic 300 Blackout rounds. The weather was mild and dry, ideal for testing the gas block’s adjustability without environmental factors interfering. Adjusting the gas block with the tool-less collar was incredibly simple, requiring only a few seconds to switch between settings using a multi-tool.
The difference in cycling between settings was immediately noticeable. I started with the most restrictive setting and gradually opened the gas port until the rifle cycled reliably with both types of ammunition. The ease of adjustment was definitely a game-changer. My only initial concern was the detent for the collar felt a little soft.
Extended Use & Reliability
After several months of use, including multiple range trips and even a carbine course, the Strike Industries Collar Adjustable Gas Block has held up surprisingly well. I haven’t noticed any significant wear and tear, and the clamp-on design hasn’t loosened despite my initial concerns. Cleaning the gas block is relatively straightforward, requiring only a quick wipe-down with a solvent and a brush to remove carbon buildup. The collar adjustment mechanism remains smooth and functional.
The Strike Industries Collar Adjustable Gas Block outperforms traditional set-screw gas blocks in terms of ease of adjustment, although it may not offer the same level of granular control. I have used other adjustable gas blocks which required shims and set screws which ended up being a tedious process. So the collar system wins in this case.
Breaking Down the Features of Strike Industries Collar Adjustable Gas Block
Specifications
The Strike Industries Collar Adjustable Gas Block features a tool-less adjustment collar, allowing for quick and easy changes to gas flow without the need for any tools. This is a significant advantage for users who frequently switch between different ammunition types or shooting conditions.
It offers 6 preset settings, including 5 pre-sized settings and one completely closed setting, providing a wide range of gas flow options. This enables the user to fine-tune the gas system for optimal performance with various loads and suppressor configurations.
The gas block is designed for clamp-on mounting, eliminating the need for set screws. This simplifies installation and potentially reduces the risk of damaging the barrel.
It is compatible with all 0.750 gas block journals, making it suitable for a wide range of AR-15 barrels. This standardized sizing ensures broad compatibility across different rifle platforms.
The gas block is finished in black, offering a sleek and durable aesthetic. This corrosion-resistant finish provides longevity and a professional appearance.
These specifications translate to a gas block that is easy to install, simple to adjust, and broadly compatible, making it an attractive option for both novice and experienced AR builders.
Performance & Functionality
The Strike Industries Collar Adjustable Gas Block performs its primary job effectively: regulating the amount of gas flowing back into the bolt carrier group. The rifle cycles reliably across a variety of loads with the correct setting. However, the “sweet spot” for each setting is a narrower than a micrometer style gas block.
One potential area for improvement is the tightness of the detent in the collar. Some users have reported that the collar can feel a little loose, which could lead to unintended adjustments, although I have not experienced this personally.
Design & Ergonomics
The Strike Industries Collar Adjustable Gas Block boasts a streamlined and functional design. The collar is easy to grip and rotate, even with gloves on. The overall weight is comparable to other adjustable gas blocks on the market, so it doesn’t add significant bulk to the rifle.
There is a slight learning curve to understanding which setting is optimal for a given load, but the intuitive design of the collar helps expedite this process. Watching the Strike Industries installation video is highly recommended.
Durability & Maintenance
The Strike Industries Collar Adjustable Gas Block appears to be built to last. The materials are high-quality, and the finish is durable. Routine cleaning and lubrication are sufficient to maintain its functionality.
There are no readily replaceable parts, so any significant damage would likely require replacing the entire gas block.
Accessories and Customization Options
The Strike Industries Collar Adjustable Gas Block does not come with any specific accessories, but it is compatible with standard AR-15 gas tubes. There are no direct customization options, but the user can certainly fine-tune the gas ports themselves with drill bits if they choose.
The clamp-on design may limit compatibility with some very tight-fitting handguards, but this is not a common issue.
