AR15 Front Sight Post Kit Review

First Thoughts on the AR15 Front Sight Post Kit

The AR15 Front Sight Post Kit is a seemingly simple, yet critically important component for any AR-15 rifle utilizing a front sight base (FSB). It’s the heart of your iron sights, allowing for precise elevation adjustments to ensure accurate shots. As someone who’s tinkered with and built countless AR-15s over the past decade, I was intrigued to see how this particular kit would perform, especially given its remarkably affordable price of $10.49.

I was in the middle of piecing together a budget-friendly AR build for a friend when I realized I needed a reliable front sight post. The existing rifle had a damaged post, rendering the front sight useless. After browsing numerous options, I settled on this kit due to its inclusion of all necessary components – the A2 front sight post, detent, and spring – at a price point that’s hard to beat.

Upon receiving the kit, I was immediately impressed by the seemingly robust construction of the parts. The finish appeared uniform and free of blemishes. The detent and spring felt appropriately strong and responsive. While I wasn’t expecting aerospace-grade materials at this price, my initial assessment was positive.

Compared to higher-end front sight post kits that often boast coatings for enhanced corrosion resistance or are machined from more exotic materials, this AR15 Front Sight Post Kit is decidedly more basic. However, for a general-purpose AR build or as a set of emergency spares, it seemed perfectly adequate. My initial thought was, “Can something this inexpensive actually hold up to the rigors of regular shooting?” I was eager to find out.

First impressions were cautiously optimistic. For a budget-friendly option, the AR15 Front Sight Post Kit appeared well-made and complete. I was excited to install it and see how it performed on the range.

Real-World Testing: Putting AR15 Front Sight Post Kit to the Test

First Use Experience

My first experience with the AR15 Front Sight Post Kit involved installing it on a completed AR-15 upper receiver. The installation took place in my workshop, which is not the cleanest of environments but serves as a functional space for gunsmithing projects. After installation, it was off to the range. It was a slightly overcast day, with temperatures hovering around 60 degrees Fahrenheit – ideal conditions for shooting.

The installation itself was straightforward, thanks to my familiarity with AR-15 platforms. The front sight detent and spring fit snugly into their respective slots within the FSB. Adjusting the sight post using an AR15 Front Sight Post Kit adjustment tool felt smooth and consistent. However, I did notice that the detent “click” wasn’t as pronounced as with some higher-end sight posts I’ve used. Still, it seemed functional.

Initially, the rifle shot a bit low, as expected with a new front sight post. A few clicks upward with the adjustment tool brought the point of impact right on target at 50 yards. The rifle performed as it should. There were no immediate issues or surprises after the first 50 rounds.

Extended Use & Reliability

After several weeks of regular use, the AR15 Front Sight Post Kit has held up surprisingly well. The rifle has seen approximately 500 rounds since the installation, with no noticeable degradation in performance or zero shift. I’ve taken it through various range sessions, including some rapid-fire drills, and the front sight post has remained securely in place.

I’ve observed no visible signs of wear and tear on the sight post itself. However, I did notice a slight amount of surface rust forming on the detent after a particularly humid range day. Proper cleaning and lubrication prevented any further corrosion. Maintenance is simple: a quick wipe down with a lightly oiled cloth after each shooting session.

Compared to my experience with more expensive, coated front sight posts, this kit requires slightly more diligent maintenance to prevent corrosion. It doesn’t outperform premium options, but given the significant price difference, it provides acceptable performance for the cost. It would be interesting to see a Manufacturer offering a version with a corrosion-resistant coating.

Breaking Down the Features of AR15 Front Sight Post Kit

Specifications

• The kit includes a standard A2 front sight post, manufactured to mil-spec dimensions for compatibility with most AR-15 FSBs. The A2 sight post is known for its simple, robust design and ease of adjustment.
• It also includes a front sight detent and detent spring, essential components for maintaining the desired elevation setting. These parts ensure that the sight post stays in place during firing.
• The sight post is made from steel, offering adequate durability for most shooting applications. The detent and spring are also made from steel for reliable function.

These specifications are crucial for ensuring proper fit and function within the AR-15’s front sight assembly. Without these components, the firearm would be unable to be accurately sighted, making it almost impossible to target effectively. The mil-spec dimensions also help ensure compatibility across various AR-15 platforms.

Performance & Functionality

The AR15 Front Sight Post Kit performs its core function adequately. It allows for consistent and repeatable elevation adjustments, enabling accurate targeting.

The primary weakness is the lack of a more pronounced “click” from the detent. This could lead to accidental adjustments if bumped hard enough. Overall, it meets expectations for a budget-friendly replacement part.

Design & Ergonomics

The design is classic A2, which is inherently functional but not particularly innovative. The materials used are standard for this type of component.

The AR15 Front Sight Post Kit is easy to use with the proper tools. There is virtually no learning curve for those familiar with the AR-15 platform.

Durability & Maintenance

Given the steel construction, the sight post should last for thousands of rounds with proper care. The detent and spring are more susceptible to wear and corrosion.

Maintenance is minimal, primarily involving cleaning and light lubrication to prevent rust. The price point makes replacement more appealing than extensive repairs.

Accessories and Customization Options

The AR15 Front Sight Post Kit is designed as a direct replacement part. There are no included accessories or customization options beyond the standard elevation adjustments.

It is compatible with any AR-15 that utilizes a standard FSB and A2-style front sight post. Aftermarket accessories such as fiber optic front sights could potentially be used, but this kit is intended to be a simple, functional solution.
