Tacfire A2 Buffer Tube Hollow Set Screw Review

Let’s Dive into Tacfire A2 Buffer Tube Hollow Set Screw

The Tacfire A2 Buffer Tube Hollow Set Screw is a seemingly simple, yet crucial component in the AR-15 platform. It’s a small piece tasked with a big job: securing the buffer tube, and consequently, the stock, to the lower receiver. I’m going to delve into the specifics of this Tacfire offering, and whether it lives up to its intended purpose.

My AR-15 build had reached the point where I needed to attach the A2 buffer tube. The original set screw was stripped during a previous fumble, so finding a reliable replacement became priority one. I needed something durable and dependable to ensure a secure fit.

Upon receiving the Tacfire A2 Buffer Tube Hollow Set Screw, I immediately noted its basic, unadorned appearance. It’s a small, black screw, nothing fancy. The initial impression was that it felt solid enough, but I was wary, given the feedback about the head type possibly differing from the advertised image.

I considered other options, including set screws from Brownells and Aero Precision. The deciding factor came down to price and availability; the Tacfire screw was readily available and budget-friendly. Ultimately, my decision was driven by immediate need and cost considerations.

My initial excitement was tempered by the user feedback regarding the slotted head. I was hoping for the Allen head screw depicted, as I prefer the greater torque and reduced risk of stripping with Allen heads. I was also slightly concerned about the overall quality, considering the price point.

Real-World Testing: Putting Tacfire A2 Buffer Tube Hollow Set Screw to the Test

First Use Experience

My first test took place in my workshop during the final assembly of my AR-15. I needed to secure the A2 buffer tube to the lower receiver to complete the rifle build. The environment was clean and controlled, and the stakes were relatively low.

Unfortunately, the Tacfire A2 Buffer Tube Hollow Set Screw I received did indeed have a flat (slotted) head. This immediately made the installation process less appealing. It was more difficult to apply sufficient torque without the fear of stripping the screw head compared to an Allen head.

I found myself having to be extremely cautious while tightening the screw. Any excessive force risked damaging the slot. It wasn’t a particularly enjoyable experience, but I eventually managed to secure the buffer tube.

Extended Use & Reliability

After several range trips and cleanings, the Tacfire A2 Buffer Tube Hollow Set Screw is still holding the buffer tube in place. So far, so good in terms of its primary function. There are no visible signs of loosening or damage.

However, the slotted head still bothers me. I’ve noticed that the slot is starting to show minor wear from the screwdriver, making future adjustments potentially problematic. I would definitely not trust this screw for heavy use or harsh conditions.

Compared to previous builds using Allen head set screws, this Tacfire screw feels significantly less secure and confidence-inspiring. The slotted head is a clear disadvantage. I’m considering replacing it with a higher-quality Allen head screw in the near future.

Breaking Down the Features of Tacfire A2 Buffer Tube Hollow Set Screw

Specifications

The Tacfire A2 Buffer Tube Hollow Set Screw is a standard-sized set screw designed for use with A2 buffer tubes in AR-15 lower receivers. TacFire specifies the product as:

• Material: Likely steel, finished with a black coating.
• Head Type: Hollow, with a slotted (flat) head.
• Purpose: Secures the A2 buffer tube to the lower receiver.

These specifications are crucial for ensuring compatibility and proper function of the AR-15. A correctly sized screw is essential for a secure and stable stock, directly impacting accuracy and handling. The material and finish affect durability and resistance to corrosion.

Performance & Functionality

The Tacfire A2 Buffer Tube Hollow Set Screw performs its primary function adequately, holding the buffer tube in place. However, the slotted head is a major drawback. This limits the amount of torque that can be applied and increases the risk of stripping the screw head.

The biggest weakness is the slotted head, which compromises its usability and long-term reliability. The primary strength is that it does, at least for now, secure the buffer tube. It barely meets expectations, primarily due to the head type discrepancy.

Design & Ergonomics

The build quality is basic, but functional. The material seems adequate for the intended purpose, but the finish may be prone to wear over time. The overall design is simple.

The slotted head design presents a significant ergonomic challenge. It’s more difficult to use than an Allen head screw, and increases the risk of damage during installation and removal. There’s a definite learning curve in terms of applying the right amount of torque without stripping the head.

Durability & Maintenance

The lifespan of the Tacfire A2 Buffer Tube Hollow Set Screw is uncertain, especially with the slotted head. Repeated adjustments may eventually damage the slot, requiring replacement. I don’t anticipate it lasting as long as a higher-quality Allen head screw.

Maintenance is minimal, but inspecting the screw head regularly for signs of wear is recommended. Cleaning and lubricating the threads can help prevent corrosion. However, any significant damage to the slot will necessitate replacement rather than repair.

Accessories and Customization Options

The Tacfire A2 Buffer Tube Hollow Set Screw itself doesn’t have any specific accessories. The primary customization is replacing it with a different set screw. There are various aftermarket options available, including Allen head screws and screws made from different materials.

The screw is compatible with any standard A2 buffer tube and lower receiver. Aftermarket set screws from brands like Brownells, Aero Precision, and Magpul are readily available and can be used as replacements. Upgrading to an Allen head screw is a highly recommended customization.

Who Should Buy Tacfire A2 Buffer Tube Hollow Set Screw?

The Tacfire A2 Buffer Tube Hollow Set Screw is perfect for budget-conscious builders who need a functional set screw in a pinch. It also works as a temporary replacement until a better option can be acquired.

Anyone prioritizing durability, ease of use, and long-term reliability should skip this product. Specifically, those who frequently adjust their stock or prefer high-quality components should look elsewhere. This is not for precision builds or those who demand top-tier performance.

A must-have modification is replacing it with an Allen head set screw. A higher-quality set screw made from durable steel is also highly recommended. This simple upgrade will significantly improve the overall reliability and user experience.

Conclusion on Tacfire A2 Buffer Tube Hollow Set Screw

The Tacfire A2 Buffer Tube Hollow Set Screw is a basic, functional component that gets the job done, for now. However, the slotted head is a significant drawback that compromises its usability and long-term reliability. The user feedback regarding the slotted head instead of the desired Allen head underscores a potential issue with product representation.

The price is certainly attractive, but the risk of stripping the screw head and the potential for lower durability make it a questionable value proposition. While it might suffice for a budget build or as a temporary fix, it’s not a component I would rely on for critical applications.

I would not personally recommend this product unless you are on an extremely tight budget and need a set screw immediately. In most cases, spending a few extra dollars on a higher-quality Allen head screw is well worth the investment. Consider this a “get-you-by” solution, and plan to upgrade as soon as possible for peace of mind and improved performance.
