Ballistic Advantage Lo Pro Gas Block Review

Let’s Talk About Ballistic Advantage Lo Pro Gas Block

The Ballistic Advantage Lo Pro Gas Block is a key component for any AR-15 build, particularly those prioritizing a sleek, streamlined profile. Manufactured by Ballistic Advantage, this gas block is designed to fit under slim handguards, making it a popular choice for modern sporting rifles. My interest in this gas block stemmed from a recent AR-15 build where I needed a reliable and low-profile option.

I was aiming for a lightweight, maneuverable rifle and the gas block’s size was a significant factor. Upon unboxing, I immediately noticed the smooth, even finish and the compact design. The Ballistic Advantage Lo Pro Gas Block felt solid and well-machined, giving me confidence in its build quality despite its small size.

I was choosing between this, a similar gas block from Aero Precision, and a clamp-on gas block from Seekins Precision. I chose the Ballistic Advantage Lo Pro Gas Block because it offered a good balance of price and reputation. The Aero Precision was a little pricier, and I wasn’t sure I needed the clamp-on feature of the Seekins for this particular build.

My first impression was positive. The size was perfect for my needs, and the finish looked durable. I was eager to install it and see how it performed at the range.

Real-World Testing: Putting Ballistic Advantage Lo Pro Gas Block to the Test

First Use Experience

I first tested the Ballistic Advantage Lo Pro Gas Block during a range session focused on zeroing my new optic and breaking in the barrel. The rifle was chambered in 5.56 NATO and sported a 14.5-inch barrel. The weather was dry and sunny, with temperatures around 70 degrees Fahrenheit.

The rifle cycled smoothly, and I experienced no issues with gas flow or cycling malfunctions. I ran about 200 rounds of various ammunition types, from budget-friendly FMJ to match-grade BTHP, without any problems. The gas block performed exactly as it should, reliably directing gas to cycle the action.

I was initially concerned about potential leaks due to the low-profile design, but the Ballistic Advantage Lo Pro Gas Block sealed perfectly against the barrel.

Extended Use & Reliability

After several months of use and approximately 1000 rounds through the rifle, the Ballistic Advantage Lo Pro Gas Block continues to perform flawlessly. There are no signs of wear or loosening, and the finish still looks great. I regularly inspect the gas block during cleaning and lubrication, and it remains firmly in place.

The Ballistic Advantage Lo Pro Gas Block requires minimal maintenance. After each range session, I simply wipe it down with a cloth and apply a light coat of oil to prevent corrosion. This is far less fiddly than some adjustable gas blocks I’ve used in the past.

Compared to other gas blocks I’ve used, the Ballistic Advantage Lo Pro Gas Block stands out for its reliability and simplicity. It outperforms some adjustable gas blocks in terms of consistent cycling. It also beats out some cheaper options I have used that have experienced issues with set screws loosening.

Breaking Down the Features of Ballistic Advantage Lo Pro Gas Block

Specifications

• Manufacturer: Ballistic Advantage.
• Finish: QPQ (Quench Polish Quench), which enhances corrosion resistance and durability. The QPQ finish contributes to the gas block’s ability to withstand high temperatures and harsh environmental conditions.
• Material: Most likely 4140 steel (although not explicitly stated, this is common for gas blocks), providing strength and heat resistance. The use of 4140 steel ensures the gas block can withstand the pressures and temperatures generated during firing.
• Profile: Low Profile, designed to fit under most free-float handguards. This allows for a wider range of handguard choices.
• Attachment: Set Screw, utilizing two set screws for secure attachment to the barrel. The set screw design provides a simple and reliable method for securing the gas block to the barrel.
• Compatibility: AR-15 platform, .750″ journal diameter. It is important to select the correct size gas block to match your barrel.
• Roll Pin: Not included, requiring separate purchase of a gas tube roll pin. This is a minor inconvenience but allows for user preference in roll pin type.
• Country of Origin: USA, ensuring quality and adherence to strict manufacturing standards. The fact that it is made in the USA gives me some confidence in the QA/QC process.

Performance & Functionality

The Ballistic Advantage Lo Pro Gas Block performs its primary function – directing gas to cycle the AR-15’s action – reliably and consistently. It provides adequate gas flow for proper cycling with various ammunition types and barrel lengths. Its straightforward design contributes to its reliability.

Its strength lies in its simplicity and reliable performance. A minor weakness is the lack of adjustability, which might be desired for fine-tuning gas flow in specific builds. The gas block excels in what it’s designed to do: reliably cycling the action without any fuss.

The Ballistic Advantage Lo Pro Gas Block meets my expectations for a simple, reliable gas block.

Design & Ergonomics

The Ballistic Advantage Lo Pro Gas Block features a simple, minimalist design. The QPQ finish provides a smooth, professional look and enhances corrosion resistance. Its compact size allows it to fit under even the slimmest handguards.

The installation process is straightforward, although it requires some basic gunsmithing knowledge and tools. The set screw design makes it easy to align and secure the gas block to the barrel. There is no significant learning curve.

Durability & Maintenance

The Ballistic Advantage Lo Pro Gas Block appears to be built to last. The QPQ finish and likely use of 4140 steel provide excellent resistance to wear, corrosion, and heat. With proper care and maintenance, it should provide years of reliable service.

Maintenance is minimal. Regular cleaning and lubrication are all that’s needed to keep it in good working order.

Accessories and Customization Options

The Ballistic Advantage Lo Pro Gas Block doesn’t come with any accessories besides the gas block itself. Customization is limited, as it’s a fixed gas block. However, it is compatible with any AR-15 gas tube and handguard designed for a .750″ gas block journal.

It is compatible with a wide range of AR-15 accessories, including different gas tubes and handguards. The gas block is compatible with aftermarket gas tubes, which can further enhance durability.
