AR-15 A2 Rifle Tuned Buffer Spring

The AR-15 A2 Rifle Tuned Buffer Spring is manufactured to tight tolerances and optimized specifically for rifle-length systems. Tuned for smoother buffer travel and consistent cycling, this spring pairs ideally with rifle-weight buffers (such as 5.2 oz / 5.90" buffers) to reduce felt recoil and improve long-term reliability.

Made from high-grade music wire (or stainless, depending on SKU), each spring is wound and heat-treated to maintain spring rate over repeated cycles. Whether you’re building a rifle-length AR or tuning an existing build for improved feel and function, this tuned spring helps you get predictable, repeatable results.

Features:

• Designed for rifle-length (A2) buffer tube systems

• Tuned spring rate for consistent cycling with rifle buffers (e.g., 5.2 oz)

• High-grade spring steel (music wire) — heat treated for longevity

• OEM-compatible dimensions and reliable fatigue life

• Ideal for precision builds, duty rifles, and tuned range setups
