Description
The Strike Industries AR10 Flatwire Spring is an economical, easy upgrade to any .308 AR system. The flatwire spring increases service life of the platform, smooths out the shooting cycle and greatly outlasts the stock spring. Increased bolt load, in addition to decreased compressing force, increases reliability in cycling and makes shooting more comfortable. At a cost not much greater than stock carbine springs, the SI Flatwire is an easy option for those either looking to replace worn buffer springs or begin new builds.
Decreased harmonics lessens system vibration for faster follow up shots
No more AR “twang”
Compatible with all standard AR10/SR25 receiver extension lengths
