Let’s Talk About JE Machine Tech A2 .223/.308 Rifle Length Buffer Tube
The JE Machine Tech A2 .223/.308 Rifle Length Buffer Tube is a foundational component for any AR-platform rifle build utilizing a rifle-length stock system. Manufactured by JE Machine Tech, this buffer tube promises compatibility with both AR-15 (.223) and AR-10 (.308) platforms, offering versatility and cost-effectiveness. Constructed from 6061-T6 aluminum, it aims to provide a robust and reliable connection between the receiver and the stock.
My journey to this particular buffer tube began when I was piecing together a budget-friendly AR-10 build. I needed a reliable, no-frills rifle-length buffer tube that wouldn’t break the bank. I was specifically looking for something compatible with a Magpul PRS stock, known for its precision adjustability and comfortable cheek weld.
Upon unboxing, the JE Machine Tech A2 .223/.308 Rifle Length Buffer Tube felt solid and well-machined, especially considering the price point. The black anodized finish appeared even and free of blemishes. The threads were clean and seemed ready for installation.
I considered buffer tubes from Aero Precision and Brownells, both reputable brands, but the JE Machine Tech offered a compelling price advantage. Ultimately, I chose the JE Machine Tech tube because it met my functional requirements without the added cost of premium brands. I was cautiously optimistic, hoping it would perform as well as more expensive options.
Real-World Testing: Putting JE Machine Tech A2 .223/.308 Rifle Length Buffer Tube to the Test
First Use Experience
My initial test took place at an outdoor shooting range, mounted on my AR-10 lower receiver with the Magpul PRS stock. The installation process was straightforward, and the tube threaded smoothly into the receiver without any binding or cross-threading. The stock attached securely, providing a stable platform.
The rifle performed admirably, with consistent cycling and no noticeable issues related to the buffer tube. The buffer moved freely within the tube, and the recoil felt manageable, even with heavier .308 loads. I was initially impressed with the tube’s performance.
Extended Use & Reliability
After several months of use, involving multiple range trips and varying weather conditions, the JE Machine Tech A2 .223/.308 Rifle Length Buffer Tube has held up reasonably well. There are some minor signs of wear on the anodized finish, particularly where the stock rubs against the tube. The tube hasn’t exhibited any signs of cracking or deformation.
Maintenance is simple. A quick wipe down with a lightly oiled cloth keeps it clean and prevents corrosion. The tube has performed adequately, although I have experienced some inconsistencies with the buffer retainer (more on that later).
Compared to other buffer tubes I’ve used, like those from higher-end brands, the JE Machine Tech offering doesn’t feel quite as refined, but it’s a solid performer for the price. It hasn’t completely blown me away, but it hasn’t disappointed me either.
