With the potential to withstand up to 15,000,000 compression cycles in just one race, this wire stock is an ideal choice for a carbine that will experience significantly less wear over its lifespan. To ensure the longevity of these springs, Sprinco employs heat treatment, shot peening, and a special formula that enhances their durability for the entire lifetime of your carbine. Opting for the Sprinco red carbine buffer spring is a smart move to enhance the long-term dependability of your AR-15/M4.

The carbine length buffer tube is an essential component in AR-15 rifles and its performance greatly depends on the quality of its recoil spring. The red spring is suitable for use with 5.56 AR-15s equipped with a carbine length gas system and 16” barrel. It has been rigorously tested by Sprinco and has shown great compatibility with other powerful cartridges such as .458 SOCOM, 6.5 Grendel, .450 Bushmaster, among others. Made from chrome silicon wire stock, this extra power spring offers superior durability and reliability. Furthermore, it has been heat treated and shot peened to ensure maximum strength and longevity, making it a top choice for AR-15 enthusiasts who frequently change their setup.
