Troy 2in Gas Block Review

Let’s Dive into Troy 2in Gas Block

The Troy 2in Gas Block isn’t just another AR-15 component; it’s a solution for those of us who demand both form and function. Manufactured by Troy, this gas block is designed to cover unsightly taper pin holes left behind after removing a standard A2 front sight, while also allowing for the installation of free-floating handguards. For those of us who value a clean, professional look alongside reliable performance, this little piece of kit is a godsend.

After years of tinkering with AR platforms, I was faced with a common issue: upgrading to a free-float rail on a barrel that had already been drilled for an A2 front sight. The exposed, unfinished barrel section was an eyesore and a potential corrosion point. The Troy 2in Gas Block promised to solve that problem, offering a sleek, low-profile solution.

Upon receiving the Troy 2in Gas Block, I was immediately impressed by its robust feel. Machined from 4140 pre-hardened steel and finished with MIL-STD Manganese Phosphate, it felt like it could withstand serious abuse. The black finish was even and consistent, promising a seamless integration with my existing AR build.

Compared to other low-profile gas blocks I’ve used, the Troy 2in Gas Block stood out due to its specific design for covering those pesky A2 sight pin holes. Many other options leave that area exposed, which defeats the purpose for someone seeking a clean aesthetic. I chose this gas block specifically for this purpose.

My first impression was definitely positive. The build quality was evident, and I was excited to see how well it would clean up the front end of my rifle after ditching the A2 sight. It felt like the missing piece to a puzzle.


Real-World Testing: Putting Troy 2in Gas Block to the Test

First Use Experience

My first opportunity to test the Troy 2in Gas Block came during a full AR-15 build intended for 3-gun competitions. The range was my proving ground, and the goal was to ensure reliable cycling with a variety of ammunition types. I also wanted to assess its heat resistance during rapid firing drills.

During that initial range session, the gas block performed flawlessly. Even after several high-volume strings of fire, there were no signs of gas leakage or performance degradation. The environment was relatively dry and temperate, which didn’t provide extreme testing conditions, but the intense heat generated from rapid firing would be a good trial.

Installation was straightforward, and thanks to its low-profile design, it cleared my chosen free-float handguard with plenty of room to spare. I didn’t need to make any adjustments or modifications.

After the first use, I noted the even heating of the gas block and the complete absence of any visible gas leakage around the block or the gas tube. I was impressed with the seal it created and the overall reliability.

Extended Use & Reliability

After several months of regular use, including multiple range trips and even a weekend carbine course, the Troy 2in Gas Block continues to perform as expected. It has proven to be a reliable component of my AR build.

I’ve observed no signs of wear and tear on the gas block itself. The Manganese Phosphate finish remains intact, resisting rust and corrosion even after exposure to rain and humidity during outdoor shooting sessions.

Maintaining the Troy 2in Gas Block has been effortless. A quick wipe-down with a CLP-soaked cloth after each range session is all that’s needed to keep it clean and functioning properly. No special tools or procedures are required.

Compared to previous gas blocks I’ve used, the Troy 2in Gas Block stands out for its superior finish and precise fit. Cheaper alternatives often exhibit rough machining or inconsistent coatings. The Troy 2in Gas Block has been more reliable and durable.

Breaking Down the Features of Troy 2in Gas Block

Specifications

The Troy 2in Gas Block is machined from 4140 pre-hardened steel, offering exceptional strength and resistance to heat and pressure. The 2-inch length is specifically designed to cover the area under a fixed A2 front sight, concealing any unsightly taper pin holes on barrels previously drilled for a fixed front sight post.

The gas block is finished with MIL-STD Manganese Phosphate, providing excellent corrosion resistance and a non-reflective matte black finish. It blends seamlessly with most AR-15 components. Made in the USA by Troy, this gas block offers users a strong choice of a quality AR-15 component.

These specifications are critical because they directly impact the reliability and longevity of the gas block. The high-quality steel ensures it can withstand the high temperatures and pressures generated by the AR-15’s gas system. The Manganese Phosphate finish prevents rust and corrosion.

Performance & Functionality

The Troy 2in Gas Block performs its primary function flawlessly: reliably directing gas from the barrel to the gas tube, ensuring proper cycling of the AR-15. I have experienced no gas leakage or cycling issues with this gas block.

Its strength lies in its simple, robust design and precise manufacturing. One potential weakness is its fixed size; it’s specifically designed for barrels with A2 front sight pin holes, so it might not be suitable for other applications. It exceeds expectations for its intended purpose.

Design & Ergonomics

The Troy 2in Gas Block features a low-profile design, allowing it to fit under most free-float handguards without interference. Its weight is negligible, adding minimal mass to the rifle.

The installation process is straightforward and requires no specialized tools beyond a standard punch and hammer. No significant learning curve is required.

Durability & Maintenance

Given its construction from high-quality steel and its protective Manganese Phosphate finish, the Troy 2in Gas Block is built to last. It’s designed to withstand the rigors of regular use in demanding environments.

Maintenance is minimal, requiring only periodic cleaning to remove carbon buildup. The robust finish is resistant to scratches and corrosion.

Accessories and Customization Options

The Troy 2in Gas Block does not come with any accessories beyond the necessary set screws for securing it to the barrel. Its primary function is to serve as a gas block and cover existing A2 sight pin holes.

It’s compatible with any AR-15 gas tube that adheres to mil-spec dimensions, and it’s designed to fit under most free-float handguards. No specific customization options are available for this gas block.
