The TacFire MAR046308A2 AR10 A2 carbon steel buffer spring is a U.S.-made replacement spring engineered to smooth out the firing cycle of your .308 AR platform rifle. Built from high-carbon steel — the same material used in piano wire — this spring is designed to absorb and control the bolt carrier's rearward movement with less audible vibration. If you've noticed that metallic "twang" when rounds break downrange, swapping in a quality buffer spring can noticeably reduce that sound and improve the shooter's experience behind the gun.
For AR10 builders and owners running the A2-pattern buffer system, this TacFire spring is a straightforward maintenance or upgrade component. It's the kind of unsung part that contributes to a smoother, quieter recoil impulse — something every long-range or precision rifle shooter appreciates. Whether you're fine-tuning a new build or refreshing an older platform, a dedicated replacement spring keeps your action cycling reliably.
TacFire components are manufactured in the USA, so you're getting domestic quality without the premium price tag. If your AR10's buffer spring has seen hard use or you simply want to dial in your rifle's feel and sound signature, this is a sensible upgrade.

The TacFire MAR046308A2 is designed for AR10 rifles using the A2-pattern buffer system and .308 ammunition. Verify your rifle's buffer tube and system type before ordering to ensure compatibility.
The buffer spring works with the buffer weight to control the bolt carrier's rearward travel during firing. A quality spring helps manage recoil impulse, reduce noise, and keep your action cycling smoothly.
High-carbon steel — the same material in piano wire — offers excellent tensile strength and resilience. This ensures the spring maintains consistent performance and resists fatigue over many firing cycles.
This is the spring component only. It is not a complete buffer kit; you will need to use it with your existing A2 buffer weight and buffer tube.
