SLR Dimpling Jig Gas Block Review

Let’s Talk About SLR Dimpling Jig Gas Block

Building an AR-15 can be incredibly rewarding, but it also presents unique challenges, especially when it comes to properly securing a gas block. More often than not, barrels lack the necessary dimples for set screws, making installation a pain. This is where the SLR Dimpling Jig Gas Block from SLR enters the picture, offering a DIY solution that promises precision and ease of use.

I’ve been building ARs for over a decade, and I’ve seen my fair share of gas block installations gone wrong. The SLR Dimpling Jig Gas Block aims to prevent those mishaps. Upon receiving it, I was immediately impressed by its solid construction.

Prior to acquiring this jig, I often relied on freehand methods or generic jigs, both of which felt imprecise and carried the risk of damaging the barrel. I considered other jigs, such as those from Brownells and KAK, but the SLR stood out due to its reputation for quality and the multiple spacing options it offered. I chose the SLR Dimpling Jig Gas Block for the flexibility it provides with different gas block configurations.

My first impression was that this was a serious tool built to last. The robust aluminum and precise machining inspired confidence, and I was eager to put it to the test on my next build.

Real-World Testing: Putting SLR Dimpling Jig Gas Block to the Test

First Use Experience

My initial test of the SLR Dimpling Jig Gas Block occurred during a recent AR-15 build intended for a precision long-range setup. I needed to install a low-profile gas block on a new, undimpled barrel. Using a bench vise and a quality drill press, I followed the (admittedly sparse) online instructions for proper setup and alignment.

The jig held the barrel securely, and the 5/32″ drill bit (purchased separately, as noted) guided the drilling process with remarkable precision. I encountered no slipping or misalignment, even when applying moderate pressure. The process, while requiring patience and attention to detail, was significantly easier and more controlled than previous methods I’d used.

After the initial dimpling, I installed the gas block and noticed a snug, secure fit, a welcome change from previous, less precise installations. My only initial concern was the lack of included instructions; relying solely on online videos required some extra research.

Extended Use & Reliability

After several months and three additional builds using the SLR Dimpling Jig Gas Block, I can confidently say that it’s a valuable addition to my gunsmithing toolkit. The jig shows minimal signs of wear despite regular use. It cleans easily with a simple wipe-down and a bit of gun oil on the drill bushing to prevent corrosion.

The 7075 billet T6 aluminum construction is proving its worth, exhibiting no signs of bending or distortion even after repeated clamping in the vise. The jig’s precision has ensured that every gas block installation has been flawless, leading to enhanced reliability and performance of my AR builds. Compared to my past experiences with generic dimpling tools, the SLR jig provides a superior level of accuracy and consistency that significantly reduces the risk of mistakes and wasted components.

Breaking Down the Features of SLR Dimpling Jig Gas Block

Specifications

The SLR Dimpling Jig Gas Block is constructed from 7075 Billet T6 Aluminum, ensuring a robust and durable tool. It is designed to accommodate five different spacing options for gas blocks, specifically: .400in, .425in, .450in, .470in, and .500in center-to-center. A 5/32in drill bit is required (not included) for creating the dimples.

The choice of aluminum provides a lightweight yet sturdy platform that resists bending and warping under pressure. The multiple spacing options make this jig versatile for various gas block sizes and configurations.

Performance & Functionality

The SLR Dimpling Jig Gas Block excels in providing a precise and repeatable method for dimpling barrels. It ensures consistent dimple placement, which is crucial for securely mounting gas blocks.

Its strengths lie in its ease of use, robust construction, and versatility in accommodating different gas block spacing. However, the lack of included instructions is a notable weakness. The jig meets my expectations for a professional-grade dimpling tool, providing accuracy and reliability that I previously struggled to achieve.

Design & Ergonomics

The jig features five position flats that allow for secure vise mounting, enhancing stability during drilling. The design is intuitive, with clear markings indicating the correct orientation and spacing for different gas blocks.

The aluminum construction ensures a manageable weight without sacrificing durability. The SLR Dimpling Jig Gas Block is user-friendly once the correct setup procedure is understood.

Durability & Maintenance

The SLR Dimpling Jig Gas Block’s 7075 Billet T6 Aluminum construction suggests a long lifespan, even with regular use. Maintenance is straightforward; cleaning involves wiping down the jig with a cloth and applying a light coat of oil to the drill bushing to prevent corrosion.

With proper care, this tool should last for many years, making it a worthwhile investment for any serious AR builder. Its robust design ensures it withstands the rigors of frequent use and storage without compromising its functionality.

Accessories and Customization Options

The SLR Dimpling Jig Gas Block does not come with any accessories. A 5/32in drill bit is essential for use but must be purchased separately.

While the jig itself doesn’t have customization options, it facilitates the installation of various aftermarket gas blocks, allowing for significant customization of the AR-15 platform. Its compatibility with a wide range of gas blocks makes it a versatile tool for any AR build.

Pros and Cons of SLR Dimpling Jig Gas Block

Who Should Buy SLR Dimpling Jig Gas Block?

The SLR Dimpling Jig Gas Block is perfect for AR-15 enthusiasts, gunsmiths, and serious hobbyists who frequently build or modify AR-platform rifles. It is an invaluable tool for anyone seeking a precise and reliable method for installing gas blocks.

Those who should skip this product are individuals who rarely build AR-15s or those who prefer to outsource gunsmithing tasks. It’s not a necessary purchase for someone who only occasionally needs to install a gas block. A quality 5/32in drill bit is a must-have accessory to effectively use this jig.

Conclusion on SLR Dimpling Jig Gas Block

The SLR Dimpling Jig Gas Block is an exceptional tool that provides precision and reliability for gas block installations on AR-15 rifles. Its robust construction, versatile spacing options, and ease of use make it a worthwhile investment for serious AR builders.

While the lack of included instructions is a minor drawback, the jig’s performance and durability more than justify its price. I would wholeheartedly recommend it to anyone looking to elevate their AR building capabilities. Don’t risk damaging your barrel – invest in the SLR Dimpling Jig Gas Block and ensure a perfect gas block installation every time.
