DoubleStar Low Profile Gas Block Review

Let’s Dive into DoubleStar Low Profile Gas Block

The DoubleStar Low Profile Gas Block is a seemingly simple component that plays a vital role in AR-15 platform rifles. Manufactured by DoubleStar, this gas block is designed to fit under most free-floating handguard systems. Its low-profile design and durable construction promise enhanced performance and versatility for AR builds.

I was looking to upgrade my current AR build, wanting to install a longer free-floating handguard for improved ergonomics and accessory mounting options. The standard A2 front sight post, acting as the gas block, was preventing me from achieving this. A low-profile gas block was the obvious solution, and the DoubleStar offering seemed like a solid, budget-friendly choice.

Upon receiving the DoubleStar Low Profile Gas Block, I was immediately impressed by its solid feel and clean parkerized finish. The weight felt appropriate for a steel gas block, suggesting a robust build. The machining appeared precise, with no visible burrs or imperfections.

Compared to other low-profile gas blocks I considered, the DoubleStar stood out due to its price point and reputation for reliability. I initially looked at models from [strike through]Noveske[/strike through] and [strike through]Daniel Defense[/strike through], but their higher cost didn’t seem justified for my build. Other budget options felt flimsy, so the DoubleStar struck a good balance.

My first impression was positive. I was cautiously optimistic that this DoubleStar Low Profile Gas Block would perform as expected and allow me to complete my AR build. The simple design and solid construction inspired confidence.

Real-World Testing: Putting DoubleStar Low Profile Gas Block to the Test

First Use Experience

I tested the DoubleStar Low Profile Gas Block during a range session focused on zeroing my newly installed optic on my AR-15. The installation process, although not part of the gas block’s performance, was straightforward. After properly aligning the gas block with the gas port on the barrel and securing it with the set screws, it was time to test for function.

The DoubleStar Low Profile Gas Block performed flawlessly through approximately 200 rounds of .223 ammunition. There were no noticeable gas leaks or cycling issues. The rifle operated smoothly and consistently.

Extended Use & Reliability

After several months and approximately 1000 rounds fired, the DoubleStar Low Profile Gas Block continues to perform reliably. There have been no signs of loosening, shifting, or gas leakage. The parkerized finish still looks new.

I’ve noticed no significant wear and tear on the DoubleStar Low Profile Gas Block. A quick wipe down with a lightly oiled cloth after each range session has been sufficient for maintenance. It appears that the simple design and robust steel construction of this gas block contribute significantly to its longevity.

Compared to a previous, cheaper gas block I used on another AR build, the DoubleStar Low Profile Gas Block is a significant improvement. That previous gas block exhibited noticeable gas leakage after only a few range trips. The DoubleStar simply performs as intended, offering a worry-free shooting experience.

Breaking Down the Features of DoubleStar Low Profile Gas Block

Specifications

• Material: The DoubleStar Low Profile Gas Block is constructed from 1045 steel, offering excellent strength and resistance to heat. This choice of material is crucial for withstanding the high pressures and temperatures generated during firing.
• Finish: The Black parkerized finish provides corrosion resistance and a non-reflective surface. The parkerization process creates a durable, matte finish that helps protect the steel from rust and wear.
• Profile: The low-profile design ensures compatibility with most free-floating handguard systems. This is essential for modern AR builds that often utilize extended handguards for enhanced ergonomics and accessory mounting.
• Bore Diameter: Designed for barrels with a .625″ gas block seat. This is a common gas block diameter for many AR-15 barrels, making it widely compatible.
• Mounting: Secured with set screws for a secure and reliable attachment to the barrel. Set screws provide a simple yet effective way to fix the gas block in place.
• Compatibility: Specifically designed for AR Platform rifles and AR-15 models. Ensures that the gas block is properly sized and configured for these firearms.

Performance & Functionality

The DoubleStar Low Profile Gas Block performs its primary function of directing gas from the barrel to the gas tube consistently and reliably. This ensures proper cycling of the AR-15 action. It does exactly what it needs to do, every single time.

The greatest strength of this gas block is its simplicity and reliability. It is a no-frills component that simply works as intended. The lack of adjustability could be seen as a weakness by some, but for a standard AR build, it is perfectly adequate.

The DoubleStar Low Profile Gas Block meets my expectations perfectly. I needed a reliable and affordable gas block that would allow me to install a free-floating handguard, and this product delivered precisely that.

Design & Ergonomics

The build quality of the DoubleStar Low Profile Gas Block is commendable, especially considering its price point. The 1045 steel feels robust and the parkerized finish is evenly applied. The gas block isn’t exactly something that is comfortable in the hand, but there are no sharp edges.

The design is exceptionally user-friendly. Installation is straightforward, requiring only basic tools and knowledge of AR-15 assembly. Even a novice builder should be able to install this gas block without much difficulty.

Durability & Maintenance

Given its steel construction and parkerized finish, the DoubleStar Low Profile Gas Block is expected to last for many years with proper care. The design doesn’t feature any complex moving parts that could be prone to failure. It’s just a hunk of steel.

Maintenance is simple. A quick cleaning with a brush and solvent, followed by a light coat of oil, is sufficient to keep the gas block in good condition. Periodic inspection for any signs of loosening or corrosion is recommended.

Accessories and Customization Options

The DoubleStar Low Profile Gas Block itself does not come with any specific accessories. However, it is designed to be compatible with a wide range of AR-15 accessories, including:

• Free-Floating Handguards: The low-profile design is essential for using most free-floating handguards, which provide improved accuracy and accessory mounting options.
• Gas Tubes: Standard AR-15 gas tubes are fully compatible with the DoubleStar Low Profile Gas Block.
• Optics and Sights: The gas block’s low profile allows for unobstructed mounting of optics and sights on the upper receiver.

The DoubleStar Low Profile Gas Block is designed to work seamlessly with various aftermarket AR-15 components. This allows users to customize their rifles to their specific needs and preferences.
