Precision Reflex Flip-Up Front Sight Gas Blocks Review

Let’s Talk About Precision Reflex Flip-Up Front Sight Gas Blocks

The Precision Reflex Flip-Up Front Sight Gas Blocks are designed for the .308 AR platform, offering a streamlined solution for those who want the option of iron sights without sacrificing the rail space needed for optics. Precision Reflex has a reputation for quality components, and these flip-up sights aim to deliver on that promise. I’ve always been a proponent of having backup iron sights, especially on a rifle intended for anything beyond casual range use.

My journey to these gas block sights started with a simple need: I wanted a reliable .308 AR build that could transition seamlessly between different sighting systems. I was piecing together a rifle specifically for hog hunting in dense brush, where a red dot is king for quick target acquisition, but I also wanted a robust backup should the optic fail or visibility conditions change. This meant avoiding bulky fixed front sights that would interfere with my field of view through the red dot.

Upon unboxing the Precision Reflex Flip-Up Front Sight Gas Blocks, my initial impression was positive. The hard-coated black anodized aluminum felt solid and well-machined, and the flip-up mechanism moved smoothly and locked securely into place. The standard A2 front post seemed robust enough to withstand abuse.

Compared to other flip-up front sight options, such as those from Magpul or Troy Industries, I was drawn to the Precision Reflex offering due to its integrated gas block design. This eliminates the need for a separate gas block and front sight, simplifying the installation process and potentially increasing the overall rigidity of the system. I also liked the aesthetic; it looked clean and purposeful.

My first impression was excitement tempered with cautious optimism. It looked promising, but I knew the real test would be how it performed under the pressures of real-world use and held its zero after repeated firing.

Real-World Testing: Putting Precision Reflex Flip-Up Front Sight Gas Blocks to the Test

First Use Experience

My initial test took place at an outdoor shooting range under sunny conditions. I mounted the Precision Reflex Flip-Up Front Sight Gas Blocks on my .308 AR build and zeroed it at 100 yards.

The sight was relatively easy to zero, although the A2 front post does require a tool for adjustments (thankfully I always keep one handy in my range bag). After getting it dialed in, I ran several magazines through the rifle, focusing on transitioning between using a red dot optic and flipping up the iron sights. The flip-up mechanism was easy to manipulate, even with gloves.

There were no immediate issues; the sight held its zero, and the flip-up mechanism remained reliable. One pleasant surprise was how little the front sight impacted my field of view through the red dot when folded down.

Extended Use & Reliability

After several months of regular use, including multiple hog hunts and range sessions, the Precision Reflex Flip-Up Front Sight Gas Blocks have proven to be remarkably durable. There are no signs of significant wear and tear, despite exposure to mud, dust, and the occasional accidental bump against brush.

Maintenance is straightforward. A quick wipe down with a lightly oiled cloth after each use is all that’s needed to keep the aluminum corrosion-free and the flip-up mechanism functioning smoothly.

Compared to a previous experience with a cheaper, non-integrated flip-up front sight on a .223 AR, the Precision Reflex offering is a significant upgrade. The Precision Reflex sight feels far more solid, holds its zero better, and the integrated gas block design gives me peace of mind.

Breaking Down the Features of Precision Reflex Flip-Up Front Sight Gas Blocks

Specifications

• The Precision Reflex Flip-Up Front Sight Gas Blocks are specifically designed for .308 Winchester AR-platform rifles. This ensures proper gas regulation and compatibility with the AR-10/SR-25 platform.
• They are constructed from T6 6061 aluminum with steel pivot pins and #10-24 cross bolts. This combination provides a balance of lightweight durability and corrosion resistance.
• The front sight uses a standard steel A2 front post for elevation adjustments. This is a widely available and easily replaceable component.
• The manufacturer is Precision Reflex, a company known for its AR-15/AR-10 components. Precision Reflex has a long-standing reputation for quality.
• The unit has a black hard-coat anodized finish. This protects the aluminum from scratches and corrosion.
• The sight is top mounted and designed for the front sight position. This is the standard location for a front sight on an AR-style rifle.
• The front blade height is 2.617 inches. This is important for proper alignment with a rear sight.
• The included accessories are standard, consisting of the front sight gas block itself. Users will need to provide their own A2 sight adjustment tool.

Performance & Functionality

The Precision Reflex Flip-Up Front Sight Gas Blocks perform their primary function – providing a reliable backup sighting system – exceptionally well. The flip-up mechanism is smooth and positive, locking securely in both the up and down positions.

The A2 front post allows for precise elevation adjustments, and the sight holds its zero consistently. The only improvement I would suggest is the addition of windage adjustment capability, which is lacking in the current design.

Overall, the sight meets and exceeds my expectations for a backup iron sight. Its robust construction and reliable performance give me confidence in its ability to function when needed.

Design & Ergonomics

The build quality is excellent, with tight tolerances and a clean finish. The aluminum construction keeps the weight down, adding minimal bulk to the front of the rifle.

The integrated gas block design is both aesthetically pleasing and functional. The flip-up mechanism is intuitive and requires minimal effort to operate. The only slight drawback is the lack of a tool-less adjustment for the front sight post.

Durability & Maintenance

The T6 6061 aluminum and steel components should provide years of reliable service. The hard-coat anodized finish is resistant to scratches and corrosion.

Maintenance is simple. Regular cleaning and lubrication of the flip-up mechanism are all that is typically required.

Accessories and Customization Options

The Precision Reflex Flip-Up Front Sight Gas Blocks themselves don’t have many customization options beyond the standard A2 front sight post, which can be replaced with aftermarket versions. The primary customization aspect is its compatibility with various .308 AR-10 handguards and optics.

The sight is designed to work with any standard AR-10/SR-25 upper receiver and handguard system. It also pairs well with a wide range of rear back up iron sights.
