The TacFire MAR046-308 AR10 buffer tube spring is engineered to smooth out the sharp metallic "twang" that echoes through your rifle when rounds downrange. Built from piano wire material, this USA-made spring handles the recoil impulse of .308 AR platform rifles with consistent, dampened performance. If you've ever cringed at that audible ring coming from your buffer tube on every shot, this spring offers a straightforward mechanical solution to tame it.
Recoil management in an AR10 isn't just about comfort—it affects follow-up accuracy, muzzle control, and how your rifle feels in sustained fire. A quality buffer spring that absorbs and returns energy smoothly is fundamental to the platform, and the MAR046-308 is built from the same material used in piano wire, known for consistent spring properties and durability across thousands of cycles.
This is a no-frills, hard-working part for AR10 shooters who want to reduce noise and vibration without chasing exotic solutions. Drop it into your buffer tube and get back to shooting. Whether you're tuning a long-range rig, a hunting rifle, or a workhorse range gun, a solid buffer spring is part of the foundation.
