The CS Flat Wire Buffer Spring is the next generation spring design. The CS round wire buffer spring was a significant step forward when compared to buffer springs manufactured from music wire. The CS flat wire spring provides another significant step forward in performance. CS Flat Wire retains all the performance attributes embodied in our CS round wire buffer spring and then enhances them.
At installed height (bolt in battery) the load on the bolt is increased by about 10% compared to our CS round wire spring. This works more energy before the bolt unlocks and provides a flatter recoil impulse. This minimizes the effect of the spring returning the bolt to battery. The CS flat wire spring requires about 6% less force to fully compress than our CS round wire spring. Less energy is bled off to the gun, resulting in reduced rifle (and sight) movement.
By design, the CS flat wire spring operates with significantly lower stresses than similar round wire springs. This improves the consistency of the spring throughout its working life. Through 500,000 compression cycles, a change in spring loading of less than 2% occurs. A conventional music wire spring can change by as much as 7% the very first time it is compressed!
