AR-15 Flat-Wire Buffer Spring, 40 Coil | 5.56 NATO/300 BLK/7.62x40 WT | 6.8 SPC II/6.5 Grendel/.458 SOCOM
The chrome silicon flat-wire spring increases service life of the AR platform, smooths out the shooting cycle, and greatly outlasts the stock spring. Increased bolt load, in addition to a more linear compression with less stacking increases reliability.
Standard power spring is appropriate for most standard AR-15 calibers.

|This part increased the reliability of my rifle dramatically and now I trust my rifle more there I ever would have before I replaced the stock spring.|

|I recently purchased the AR Flat Wire Spring and found it does work well in a Carbine Length Gas Tube when firing a 6.8 SPC.|
