Let’s Talk About JE Machine Tech A2 Buffer Tube Screw
The JE Machine Tech A2 Buffer Tube Screw is a seemingly simple component in the AR-15 platform, but crucial for securely attaching the A2 stock. It’s the unsung hero that keeps your rifle shouldered and ready. This little screw, manufactured by JE Machine Tech, ensures a stable shooting platform, allowing for consistent accuracy and control.
I needed to replace the stripped screw on my trusty AR-15 A2 stock. Years of range trips and tinkering had finally taken their toll, leaving the stock wobbly and impacting my accuracy. I’ve always favored the A2 stock for its simplicity and ruggedness, and a secure buffer tube screw is non-negotiable.
Upon arrival, the JE Machine Tech A2 Buffer Tube Screw was in a small, unassuming plastic bag. My initial thought was that it looked…small. It was certainly lighter than I expected, and the hex head design raised an eyebrow, considering A2 stocks traditionally use a flat head screw.
I’ve used buffer tube screws from Brownells and Aero Precision in the past. I ultimately chose the JE Machine Tech offering because of its attractive price point, figuring it was worth a shot for such an inexpensive part. My first impression was cautiously optimistic, tinged with a bit of apprehension due to the hex head.
Real-World Testing: Putting JE Machine Tech A2 Buffer Tube Screw to the Test
First Use Experience
I tested the JE Machine Tech A2 Buffer Tube Screw at my local outdoor range. It was a slightly overcast day with a light breeze, typical conditions for central Texas. The immediate challenge was the hex head design; my A2 stock was designed for a flathead screw, meaning this one sits inside the buffer tube cavity, making it difficult to access and torque correctly.
The weather was mild, but the threads on the screw felt a little gritty during installation. Even with careful tightening, I couldn’t achieve the same rock-solid lockup as with a traditional flat head. The initial wobble was gone, but a slight creak remained under pressure, which was concerning.
Extended Use & Reliability
After a few weeks of use and about 300 rounds downrange, the JE Machine Tech A2 Buffer Tube Screw’s performance has remained…adequate, but not confidence-inspiring. There are no visible signs of wear and tear on the screw itself. However, the slight creak persists and I find myself checking the tightness before each shooting session, which is a habit I never developed with my old flat head screw.
Cleaning and maintenance are straightforward; a quick wipe-down with a little CLP is all it needs. Compared to my previous experiences with mil-spec flat head screws, the JE Machine Tech offering feels like a noticeable step down in terms of security and peace of mind. It works, but I wouldn’t trust it in a high-stakes situation.
Breaking Down the Features of JE Machine Tech A2 Buffer Tube Screw
Specifications
The JE Machine Tech A2 Buffer Tube Screw is a steel screw designed to secure the A2 buffer tube to the lower receiver. According to the manufacturer, it is designed to be a durable and reliable replacement part. It features a black finish for corrosion resistance and comes in a quantity of one.
- Manufacturer: JE Machine Tech
- Quantity: 1
- Color: Black
The issue arises with the screw’s design. It’s a hex head (Allen key) screw, despite the implication that it’s a standard A2 replacement, which typically uses a flat head. This seemingly minor detail drastically affects its compatibility and effectiveness with standard A2 stocks.
Performance & Functionality
The JE Machine Tech A2 Buffer Tube Screw technically performs its basic function: securing the buffer tube. However, the smaller hex head makes it difficult to properly torque and doesn’t sit flush within the A2 stock cavity. This leads to a less secure fit and potential movement under recoil.
The strength of this screw lies in its cost-effectiveness. But, its main weakness is its poor design choice for a standard A2 stock application. It meets the bare minimum expectations but ultimately falls short in terms of providing a secure and reliable platform.
Design & Ergonomics
The build quality appears decent, with a solid steel construction and a black finish. However, the hex head design is a significant ergonomic drawback. This design makes it difficult to access, tighten, and visually inspect the screw once installed in a standard A2 stock.
There is a slight learning curve in trying to properly torque a hex head screw in a flathead stock cavity. Its design is not user-friendly, especially compared to the simplicity of a traditional flathead screw.
Durability & Maintenance
The steel construction suggests decent durability. However, the less-than-ideal fit could accelerate wear and tear on the threads of both the screw and the lower receiver. Maintenance is simple: a quick wipe down with a little oil.
Accessories and Customization Options
No accessories come with the screw; it’s a standalone replacement part. Customization isn’t really applicable to a buffer tube screw. Its function is simple: to secure the A2 stock. The hex head design might be compatible with some aftermarket hex-head A2 stock adapters (if they exist).
Pros and Cons of JE Machine Tech A2 Buffer Tube Screw
Pros
- Cost-effective replacement part.
- Durable steel construction.
- Black finish provides some corrosion resistance.
Cons
- Incorrect hex head design for standard A2 stocks.
- Difficult to properly torque and secure.
- Potential for movement and wobble under recoil.
- Misleading product description and/or image (flathead vs. hex head).
Who Should Buy JE Machine Tech A2 Buffer Tube Screw?
This screw might be suitable for someone on a very tight budget who is desperate for a replacement and doesn’t mind a compromised fit. It could also work for a builder using a non-standard A2 stock that specifically requires a hex head screw (though these are rare).
Avoid this product if you are looking for a direct, reliable replacement for a standard A2 stock. If you are prioritizing a secure and wobble-free shooting platform, seek out a traditional flat head buffer tube screw instead.
Conclusion on JE Machine Tech A2 Buffer Tube Screw
The JE Machine Tech A2 Buffer Tube Screw is a case of getting what you pay for. While inexpensive, its incorrect hex head design makes it a poor choice for most standard A2 stock applications. The value proposition is questionable, as the compromised fit and potential for wobble outweigh the minimal cost savings.
I personally cannot recommend this product for anyone seeking a reliable and secure A2 stock attachment. There are better alternatives available that offer a proper fit and peace of mind. Spend a few extra dollars for a mil-spec flat head screw; your shooting experience (and your rifle) will thank you.
