Strike Industries ARFWSP AR Flat Wire Spring - Pistol Length

The Strike Industries AR Flat Wire Spring (ARFWSP) is a pistol-length buffer spring engineered for the AR-15 platform. Machined from Cryo-Cycled 17-7 PH steel, this flat wire replacement spring stores more energy in a smaller footprint than a conventional round-wire spring, delivering longer service life and a noticeably smoother bolt cycle.

At a compact 10" overall length with an 0.94" outer diameter and 0.75" inner diameter, the ARFWSP drops directly into any pistol-length AR buffer tube and is specifically designed to eliminate the audible "AR twang" that occurs when the bolt carrier runs back over a standard buffer spring. The flat wire profile packs more material into each coil for improved resistance to set and fatigue over thousands of cycles.

Whether you are building an AR-15 pistol, refreshing a worn-out spring, or just chasing a quieter and more reliable cycle, the Strike Industries AR Flat Wire Spring is a straightforward drop-in upgrade for any pistol-buffer setup.
