Let’s Talk About TacFire MAR046-308 AR10 BUFFER TUBE SPRING MAR046308
The TacFire MAR046-308 AR10 BUFFER TUBE SPRING is a seemingly simple component, but it plays a vital role in the AR10 platform’s reliable cycling. This spring, manufactured by TacFire, is designed for AR10 rifles chambered in .308/7.62 and intended for use with 6-position buffer tubes. It aims to provide consistent pressure and smooth operation, ensuring reliable cycling of the bolt carrier group.
As someone with over a decade of experience building and maintaining AR-style rifles, including numerous AR10s, I’ve seen firsthand the impact a quality buffer spring can have on performance. My current AR10 build was exhibiting inconsistent cycling, sometimes failing to lock back on an empty magazine, pointing towards a weak or worn buffer spring. I needed a reliable, affordable replacement to get my rifle back in top shape.
When the TacFire spring arrived, I was initially surprised by its unassuming appearance; it looked just like any other buffer spring. However, closer inspection revealed a consistent coil diameter and a clean, black finish. It didn’t have the “high-end” look of some more expensive springs, but it felt solid and well-made for the price point.
Compared to a few other budget-friendly buffer springs I’ve used, the TacFire seemed to have a slightly firmer compression. I considered a more expensive, brand-name spring, but the price of the TacFire was too appealing to ignore, especially as a potential quick fix. My first impression was cautiously optimistic; I was eager to see if this budget-friendly option could restore my AR10’s reliability.
Real-World Testing: Putting TacFire MAR046-308 AR10 BUFFER TUBE SPRING MAR046308 to the Test
First Use Experience
I tested the TacFire MAR046-308 AR10 BUFFER TUBE SPRING at my local outdoor shooting range. It was a relatively mild day, around 65 degrees Fahrenheit with a slight breeze. I ran approximately 100 rounds of various .308 ammunition through my AR10, including both surplus military rounds and commercially manufactured hunting loads.
The immediate improvement was noticeable; the rifle cycled much smoother, and I experienced no failures to lock back on an empty magazine. Even with the heavier hunting loads, the spring provided sufficient resistance to prevent excessive bolt carrier speed. The recoil felt slightly more manageable compared to the old, worn spring.
There were no immediate issues after the first range session. The installation was straightforward, and the rifle cycled flawlessly.
Extended Use & Reliability
After several weeks and approximately 500 rounds, the TacFire MAR046-308 AR10 BUFFER TUBE SPRING continues to perform reliably. There are no visible signs of wear or deformation, and the rifle continues to cycle smoothly with various types of ammunition. The black finish is still intact, with no flaking or corrosion.
Maintenance is minimal; I simply wipe down the spring with a lightly oiled cloth during routine rifle cleaning. Compared to my previous experiences with other budget buffer springs that quickly lost their tension, the TacFire has exceeded my expectations in terms of durability and consistent performance. It hasn’t disappointed me so far, particularly given its very low price point.
